Find Intercept For Nonlinear Data Sets
Nov 15, 2006
I have time (T) as a common variable located in cells A1:A9000. I also have two large data sets in columns B and C (cells B1:B9000 and C1:C9000). If I put them into an X,Y Scatter chart it is easy to see that at some point in time (perhaps around cell A3000) the slope in data set B will begin to rise and eventually the two curves will cross. I would like to find the intercept point and/or an estimate of that point (if it does not exist in the data set) and have the corresponding time reported in a set cell.

i found this vb code the other day on this forum from a post made way back in 2005 i think it was. I've found it really useful for what i wanted to do, but i wonder if it can be expanded or changed to allow for more sets of imformation.
This is the Code, it finds all possible combinations from 3 sets of 3 results.

I have 5 and 6 digit transaction references in one column. Is there a quick way of finding the max and min values of both the 5 & 6 digit sets ?

2 columns from a table are:
Bill# Rates
1715 500
1715 600
1715 625
1716 750
1717 760
1717 780
1718 400
1719 650
1719 800
So there is a bill number with multiple rates. I want to find out the minimum rate for each bill number (for 1715 it is 500 and so on). Whats the easiest way to give a formula for each bill so it does it automatically? I know of SUMIF and COUNTIF but how to "MINIF"?!

I have data that consists of a set of coordinates that is indirectly related to an angular measurement. The data set that I have consists of four sets of coordinates and four coresponding angles. The data is below.
angle,43.09,34.83,26.8,18.08,
X,174.24,187.45,202.18,213.87,
Y,140.13,121.84,103.3,81.46,
How can I get excel to give me values for X and Y based on an angle that I input, such as 22.45. plotting a graph of the X and Y gives a curved output, so the methods that I know of do not seem to be working.
I have other more complex sets of data with complex curves that I would like to use a similar method to mine data.

Below is a nonlinear model, together with calibration data for which I would like to find the parameters Ro, Kc, a and b.
R = Ro + Kc * (1/(1 + exp(-(a + b*lnC))
Calibration Data
C R
0.00.3347
4.80.4201
7.70.5141
11.20.6177
14.40.6887
Given the calibration data above, how can I calculate or at least estimate these parameters?
I do not want to use an add-in program, like Solver, in Excel. I do, however, want to be able to use any existing functions, if necessary, in Excel. i'd appreciate it if someone can walk me through the steps.

What I'm attempting to do is find what are the CLOSEST four indicator prices in data set #1 are above (r1, r2, r3, r4) and below (s1, s2, s3, s4) the closing price in data set #2. Also, I can only use the indicator numbers in data set #1 that are on or before the close price date in data set #2. Because of this, not all of the r's and s's will be filled in.
I would like to use just regular excel formulas, but I have a feeling that VBA may be my only option.

I have a system of 3 equations with 3 unknowns that I would like to solve in Excel.
The equations are
24.792 = A*e^(B/(100-C))
9.857 = A*e^(B/(70-C))
4.590 = A*e^(B/(40-C))
Where e is the exponential function.

When you use a formula like intercept. It wants its ranges in 2 columns. for example, intercept(A1:A5,B1:B5).
How can I get intercept to work using the ranges in 1 row. for example, intercept(A1:D1,E1:H1).
I want to do many intercepts in a large data range and still filter by some other variables that go along with these intercepts.

Below is a series of sets. Column A is the set number. I need a macro that will insert a row between sets and then put a border around each set. In my spreadsheet the sets are from A1:C500. Sometimes the sets are only 1 row, sometimes multiple rows. It looks like I will be doing one of these sheets every week. So far I have been doing it manually, but a macro sure would save some time.

I am working on large sets of data (more than 50,000 rows of data). I have two sets of data. Set 1 and Set 2 (master data) on the same worksheet. Both the sets of data have three columns each. I am using EXCEL 2007. I was able to accomplish step 1 below.. but I am totally lost with step 2 since i have an additional criteria for the "year".
I have attached the excel sheet as well. This is what I am trying to accomplish:
1) I want to find exact matches in set 1 and set 2 and highlight it or do something to show that a match was found. The challenge is the data in set 1 can occur anywhere in set 2.
2) Add to the complication .. my criteria for matching the year is different. If the Set 1 "year" is equal to or greater by 1 yr or greater by 2 yr when compared to Set 2 "year", I want to treat it as a "match".
For example, from the data attached:
Set 1 data in row 4 is: ATLANTIC ABSECON 2004
Set 2 data in row 3 is: ATLANTIC ABSECON 2003
I want to treat these two data as "MATCH" since ATLANTIC matches ATLANTIC, ABSECON matches ABSECON and according to one of my criteria for year, Set 1 "year" is greater by 1 yr than the Set 2 "year".

I have tried nested ifs and vlookup to compare two sets of data and change the first set of data if it is than the first. But leave it alone if it either is the same or does not exist in the new set of data. It sometimes seems to work but i find it is not consistant. It looks simple but i think i am missing something.
if column A has identifiers and column B has results then it should work if the identifiers in column C are found in column A and it looks to see if column B and D are the same, then change B if different but leave it if either it is the same or not there.

I have two sets of data for students. One set contains all the students with certain test scores, taking up columns A to N. The other set contains about 80% of those same students with a different set of test scores. Students are sorted by ID numbers. How do I combine the second set into columns O to V so that student ID numbers match and it inputs the rest of the student data into the sheet.
I know there will be some blanks because not all students will be there but I need them to match up, even with the blanks.

I created a macro that extracts two columns of numbers from one workbook and need to match them to another set of numbers in another workbook. For instance i have numbers like...
18314 907
18272 64
11005 907
11005 324
..Now i need to match these numbers up with the others to find the hyperlink associated with them.

I'm attempting to create a mailing list for the company I work for, but the software that has the data record is very limiting. The two tables I received from the program are listed:
Customer
Number of Sales
name 1
#
name 2
#
name 3
I tried to illustrate that the address list has a different customer composition than the sales list; the address list has customers that the sales list doesn't have. This means I can't just sort alphabetically and drag the addresses over. My goal here is to create a datasheet that incorporates both the address and number of sales so that we can send the top 500 customers a mailing. How can I do this?

In the attached workbook, I have identical sets of data in column A separated by an blank cells. I need a macro for user form that searches for an item indicated in the textbox of the form and then delete the whole row in all sets of data.
It is important to keep the blank cells between the sets constant, 4 blank cells between each set, except the first set that starts with 3 blank cells.

I’m trying to get the total number of participants in two different sets, with selection criteria attached to both (I’ve attached an excel file, as the example with those scoring +ve highlighted in yellow). The first set A (b1:b15) I want to select all values above 5, and the second B (c1:c15) set above 10. There other provisor, is that the A and B are further split into two groups (one above and one below 20).
In summary, I need to count all the A>5, B>10 (And both have to be above 20 in column D), but not to double count the ones that have Both A>5 and B>10. I don’t want any duplicates to be counted, so summing the total of A and adding it to B won’t work. In essence it’s an attempt to use the A Union B function that you’d observe when using venn diagrams.
Is there a simple way/formula of doing this?

I manually reconcile two sets of data every month by sorting by PO# and then manually matching up the onse that are the same and then calculate if there is a variance in $ amount.
The 1st set of data is a list of invoice PO#'s and invoice $ amounts and the 2nd set of data is order PO#'s and order $ amounts. What I need to do is reconcile the orders to the invoices by PO#. It is very common to have a PO# on each list but have a different $ amount and I only need to know what the difference is between the order amount and the invoiced amount. I also need to know what is on the invoice list and not on the order list and vise versa....

I am wondering if it is better to do this in excel or access. I am pretty familiar with access...i know this would be easy to do if querying from one table and doing a relationship between identifier, but i'm not sure how to capture data from both tables. But basically this is what I want. I have 2 files, which have identifiers and share amounts...both files will have some like identifiers, some not alike...basically this is what I want to do: ....

I'm trying to compare two sets of data on the same sheet. Each set has 4 columns...A - D and F - I. I would like to take the data from D and I (range 20 to 50) and compare them to see if any differences exist in the two columns. If there is something different I would like to bold and highlight the cells (A-D) in that row, and the same goes for the second set of data (F-I).
I'm trying to do this with macros so I can add it into my existing code.

I have 2 sets of data/array/range. Each set consists of 2 columns with a large number of rows.
I want to compare my 2nd data to a master data. And list if anything is different in 2nd set of data from master set in column A than highlight the difference or copy the value to another place.
Also want to compare the 2nd column if column A was same and consider both column A and column B for that associated row different if column B is different.
The trouble for me comes in because the list is never alphabetical (sort doesnt work cause of funky naming) and never of the same size.
Attached is a photo of an example for maybe an clearer understanding. Also attached an example excel sheet I tried it within excel but cant seem to figure out how to look also for the 2nd column, so im trying to avoid the within excel route and go using vba ...

I am trying to compare two sets of data.
I have a set of All zip codes in 10 counties in one worksheet:
ex:
Column 1 / Column 2
30303 / Fulton
30307 / Fulton
30310 / DeKalb
30234 / Cobb
But this sheet has about 300 zip codes
Then in a second worksheet I have dollars by zip
30303 / $10,000
30456 / $56,000
I'd like to make a third column in this sheet that fills in what county. Does anyone know how to search sheet one for the appropriate zip, then stick the word beside that zip into the column 3 secion of the dollars by zip code?
I'd rather not have to search every zip code in the dollars section one at a time. Not all the zip codes in the state are represented in the second sheet, so it's not quite as simple as just lining them up.

ID stands for index of difficulty, the graph is supposed to indicate that as the index of difficulty increases (3) movement time increases and as it decreases (2) movement time decreases.
