Derive Curve From Values Then Apply Curve To Another Dataset?
Jun 5, 2014I have a data set (Set#1) that consists of a positional rank (1-240) and a dollar value ($46-$1) for each positional rank. It's not a straight line set.
DataSet.JPG
What I need to do is take that curve and apply it to another data set (Set#2) (1-240) and assign a dollar value ($46-$1) to each positional rank.
A "corner cutting" way of doing it would be an Index/Match to simply carry over the dollar value from (for example) #45 from my Set#1 to #45 in my Set#2. This could work reasonably well with data sets of the same size, but mine aren't always the same size, so I need to apply the curve itself. I
Using VBA In Patch Model To Change VBA In User Model
Jan 11, 2007I have some Excel models out in the field with some old VBA code that is now causing problems. I regularly develop 'patch' models to make updates or repairs to user models, but need the VBA code syntax to get into a Worksheet module and change one line of VBA code.
The worksheet is named 'Forecast' and I need to change line 5 of my VBA code.
The vast majority of my users are on Excel 2000. I remember the security issues with newer Excel versions and can walk then through that, but I forgot the code syntax I need to get the job done.
Count Based On Group Membership
May 15, 2014I would like to get the number of countries that a given "Name" has Partners in. (See example sheet for an illustration)
I have the ID of a group in column A. Column B represents Names. Column C gives Info about the country of "Name".
In column D I would like to get the information how many unique countries a "Name"'s group members are from. This means, not only within a single group, but in total over all groups. This means, that every same Name has the same number of countries in column D.
Formula in words:
"Sum of all unique countries in column C, if ID in column A matches any ID of Name in column B".

Jan 28, 2009I'd like to apply a curve to a column of student exam grades and have the curved grades displayed in the adjacent column. Here is how I'd like to curve:
I like to make a linear function out of two coordinate pairs.
First Pair (x1,y1) = (Highest Exam Grade, 99) = (H,99)
Second Pair (x2,y2) = (Class Exam Average, Desired Exam Average) =(C,D)
Slope = (99-D)/(H-C) = m
Linear Function = Y-y = m(X-x) = Y-99=m(X-H)
Each student grade would = "Y" i.e. Y=m(X-H)+99

For example. Let's assume that I want to forcast growth from January through December. I know that in January I will have 100 units. In December, I will have 1,000 units. Is there a formula to predict the the units in Feb-Nov (using a normal growth curve)?
Calculate Best Fit Equation Of Curve
May 16, 2008I am trying to calculate the equation of a curve which best fits some data. On the x-axis is date and y-axis the readings. The curve is quadratic, so on the chart I am fitting a 2nd order polyomial and displaying the equation. To prove that the equation the trendline gives me is reasonable, I am applying the equation on the x parameter to get the y parameter estimate and looking to see the error between predicted and actual - see attached.
The equation and the output from it are clearly rubbish, even though on the graph the trendline is a reasonable fit - see attached. Has anyone any ideas why? I think it has something to do with using a date on the x-axis but no idea why. Is there a way to correct for this? I also tried using the following I to calculate the coefficients which came up with a reasonable forecast (although linest should only be used for linear data): =LINEST(C3:C15,B3:B15^{1,2,3})
Create S Curve Based On Dates
Apr 4, 2014I am working on Project Planning, I need to create the Progress curve for our Project based on Weight Factor every month.
I need to create the Plan and actual curve based on the dates defined in particular activities. Once the activity progress is calculated every month based on cut off date then it will sum product with corresponding WF to get the progress achieved every month. Presently I am calculating the values every month and pasting the values in Chart data every month. I had created the S Curve and attached here.
Now my objective is to automatically calculate the values for the entire cut off date at one time (From Project Start to End). i.e I don't want to do any manual work in the Chart. I will update only the actual Dates in the file, then the curves need to get automatically updated.
1) I don't want to calculate the progress for individual activities, I would like to calculate the overall progress directly.
2) When I change the Cut off date, then the previous values needs to become static.
Formula To Distribute A Value Along A Bell Curve.
Nov 19, 2008I'm trying to find a formula that would spread out a value amongst multiple cells along a bell curve. Say I have $x,xxx. I want to spread that amount out in a certain proportion, regardless of how many cells I'm spreading it throughout.
Say I have a $10,000 project. I want to be able to spread it out like a bell curve in the cells I choose. For instance, if it was a five month project it would be distributed as
January - $1,000
February - $2,500
March - $3,000
April - $2,500
May - $1,000
If I added another month it would change to
January - $833.33
February - $1,666.66
March - $2,500.00
April - $2,500.00
May - $1,666.66
June - $833.33
I already thought of manually adding percentages to each cell, but the formula needs to be dynamic.

Model For Payment Schedule
Aug 20, 2013I'm currently developing a model for a payment schedule. For example, lets say a customer purchases an item from a store, but the store receives that payment in the following month. I'm looking to develop a dynamic model so that if I change the assumption from 1 month to another term (2,3,4+ months etc.) the model will adjust accordingly.
I've started with a formula
=IF(MONTH(H3)-MONTH(G3)=B14,G11*B13)
But of course this will not work once the term is set to larger than 1 month. With B14 representing 1 month, and G11*B13 being payment information (price * quantity).
Change Model To Category?
Apr 13, 20141. In column A, I have models, in column B, I want to place either a "printer" if the model begins with Phaser or Laser, and if it begins with WorkCentre make it MFD. Also, if the Phaser has MFP on the end, make this an "MFD" and If Color 560 or Docucolor, make this "Out of Scope". How do I read the first part of the string in column A to do this, or do I need to make a second column with this Phaser and WorkCentre broken out?
I have this code attached, but only works if I have the word Phaser or WorkCentre.
