Different Results When Using Forecast And Trend Function

Aug 29, 2013

I am forecasting some numbers and I wanted to see which function would be best suited for my task. I used the TREND function and then the FORECAST, I was expecting the same results but appeared to have slight differences.

TREND Function For Passenger Forecast

Feb 10, 2008

So I'm trying to forecast the number of passengers for an airport based on their past 7 years performance. I used "TREND" to forecast the passenger number from 2008 through to 2012 with a little problem and the numbers seems reasonable. However, When I do a scatter diagram and add a trend line, my R squared value is VERY low something around 0.03. I have a limited statistical knowledge but I assume this value should be above 0.90 in order for a good fit with trend line.

Forecast Linear Trend Between Min & Max

Jan 4, 2007

I am using the Forecast formula to give me a value from a Linear trend. However I need to limit the resulting value that is displayed within a min and max value. Background: This is to allow me to calculate the amount of bonus someone will earn depending on the Percentages of their target they achieve. The min bonus is 25% when 80% of target is achieved and max bonus is 100% when 125% or greater of target is achieved.
So the Forecast formular works great using the existing values, but i need help limiting the results to between 25% and 100%. I was trying to use a sumif formula to copy the resulting cell but only if the value fell between the 25 and 100%. I've attached the spreadsheet as I think it will highlight what i'm trying to do better than I can explain it.

Convert 52 Week Rolling Forecast To Monthly Forecast

Apr 4, 2014

I have a 52 week rolling forecast that I would like to have displayed in each calendar month that it corresponds to. I have come up with a solution where it does lump the data together into months but it is not a smooth lumping of the weeks as some weeks cross over from one month to the next. Is there a way to lump each week into its respective month. My current solution places in some months 4 weeks worth of data and in other months 5 weeks worth of data. Attached is the spreadsheet that I am using. The tab "Weekly Sales" is the 52 week data which has specified the exact dates on the calendar that that week represents. The "Monthly Sales" tab has the 12 week data which has specified the exact dates on the calendar that that month represents. I've tried SUMPRODUCT but that is giving me 4 weeks in some months and 5 weeks in others.

Getting Sum Of Periods With Trend Function

Nov 23, 2011

When using the Trend function, I can get the value for individual future periods. I then can get a total for the year by summing each individual future period.

What I don't know how to do is sum them all using one formula. For instance, If I know the values of periods 1-5, how would I write a formula that would sum the future values (in one cell) of periods 6-12 -- without having to sum each future period individually?

TREND Worksheet Function In VBA

Sep 6, 2006

I am trying to use VBA to find a value on a trendline. I have been unable to call the TREND function from Excel, and I can't see what I'm doing wrong. I'm using the following line of
point25 = WorksheetFunction.TREND( Range("d2:d25"), Range("c2:c25"), 25)

I keep getting "Runtime error 1004 - Unable to get the Trend property of the WorksheetFunction class".

TREND Function Calculate 2 Possible Y Values Along A Line

Mar 25, 2014

I currently have in my equation the trend function to linear extrapolate the date a line would cross either my upper or lower limits (100.1 and 19.9) between 2 data points. However if the 2 data points span both the upper and lower limits (as per the 2 attached examples) then unfortunately the trend function is only able to return the 1 date (where I've specified the x value). Is there any way for the TREND function to trend the 2 values? Do I simply add the 2nd x value to the new x's?

I have attached both the data and their graphs to visually explain my problem : EF Workbook.xlsx

Mid Function Returns Odd Results

Jun 1, 2006

I'm using the following phrase out of a much longer expression to
demonstrate that the return value of the MID function seems to be nothing I
can understand.

This expression:

=MID("6/10x",1,FIND("x","6/10x)-1))

returns 6/10 as text which makes sense. However I was under the impression
that when text in Excel contains numeric characters, it can be interpreted
as a number. So then how does the following expression,

=MID("6/10x",1,FIND("x","6/10x)-1)*1

return the result 38878? Does it still think it's text?

IF Function And Displaying Results As Words?

Jan 18, 2014

I am having trouble with some formulas displaying the results of the logical test as words.. For example.

=IF(E4>F4,100, IF(F4>E4, 200))

That works perfectly but I want "100" to be "Valid" and "200" to be "Invalid"

However...

=IF(E4>F4,Valid, IF(F4>E4, Invalid))

only results in the #NAME? error for me?

Sum Function To Reflect Results Across Sheets

Aug 4, 2014

I am trying to sum the details from sheet2 in sheet3. I am currently using a plain formula to sum-up the values. However, create a indirect and vlookup function to sum the values.

In sheet3, I have to sum the values from sheet2 based on the contacts. Sheet1, sheet2 and Sheet3 are connected and any update(insert,delete.. etc) will be made in sheet 1 only. Sheet2 automatically updates based on sheet1. Similarly, Sheet3 should also update based on sheet1 and sum the values based on contacts from sheet2.

I have added the formula which I am currently using in the sheet.

Subscripting Results Of SPLIT Function

Jul 15, 2014

I have a macro that loops through a column of cells to retrieve a price that is buried in a string. The cells in this column are formatted one of two ways. Either they are completely empty, or the following pattern of string is entered: "$181.27 ea. for 12 on 5/21/14" (the quotes are not part of the string entered). What I need my macro to do is pull out "$181.27" and then drop the dollar sign and then do some more math before inputting a result in a different cell, but the prices range from less than a dollar to over $100,000 so I need to use split instead of left. Should be simple, yes? Here is what I have:

[Code] ......

But I get an error 9: subscript out of range on the line that calculates PriceSplit whenever it encounters a blank cell.

I'm trying to have three different possible results from one formula based on one cell.

If A1 is greater than 10 I want B1 show 5, AND if A1 is less than -10 I want B1 to show -5, AND if A1 is between 9 and -9 I want B1 to show the value of A1/2.

I've never used logic functions in excel before.

Isblank Function Erroneous Results

Sep 1, 2009

Using data of unknown origin in Excel I found Isblank was giving a FALSE result on some apparently blank cells while giving a TRUE result on others.

Even if I used TRIM and CLEAN functions on the offending data and pasted the resulting values back the the original locations, the Isblank result was still FALSE. Also, the font colour was not set to white or transparent.

However, if I selected the cell with the 'invisible' data, clicked in the Formula Bar and pressed Enter without entering any new data, the problem disappeared for that cell. The problem also disappeared if I selected the problem 'blank' cell and pressed delete.

Can anyone explain this 'invisible data' and tell me how I can detect it using a function or formula?

On a separate sheet, I want to be able to type in the phone number in range ("O11:Q11") and have a list of invoice numbers and dates matching that phone number appear in Columns R and S respectively.

Here is some workbook info:

Invoice generator is in 'phonelookup'

Count Unique Results: Function &lt;&gt; Filter

Dec 27, 2007

Data: four variables A,B,C and D from A2:D6000

I want a count of unique D values
when A=xxx
and B=yyy
and C=zzz

I have named the A,B,C,D ranges as RangeA, RangeB, RangeC, RangeD

I have used the function

=SUM((RangeA="xxx")*
(RangeB="yyy")*
(RangeC="zzz")*

But what do I use to count-unique values of variable D ?

=SUM(IF(FREQUENCY(RangeD,RangeD)>0,1)) doesn't work.
=SUM(1/COUNTIF(RangeD,RangeD&"")) doesn't work either

They don't work because D can occur during different combinations of A,B and C. In other words, the D value of 'Smith' can, and does, occur when A is 1,2 or 3 and additionally when B is Pass, Fail, Withdrawn.

They "don't work" because I can use filters on A, B, C and D to see what the correct answer should be .. and the function doesn't return the correct answer.

I hope I've explained this ok - I've been searching on several excel-help websites for 2 days now and one of the days my client is going to want some results.

Array To Match Several Results Within SUMPRODUCT Function

Aug 25, 2008

I'm using a formula (with the SUMPRODUCT function) within which I need to match the month & year from an array with 3 "true" possibilities...

Meaning that if data (month & year) from the array matches any of the 3 months & year of a specific quarter (for example July 08, August 08, September 08), the result of that section should be "True".

The data to be matched (any of the 3 months of each quarter) is drawn from a table header (showing every month of the year) by using this "monthly" formula:

TEXT(H7;"mm.yyyy") where H7 holds "01.07.2008" (but displays "Jul. 08") and returns "07.2008".

I'm trying to extend it to something like:

TEXT({H$7;I$7;J$7};"mm.yyyy") to match either July 2008 (H7), August 2008 (I7) or September 2008 (J7) for the 3rd quarter of 2008 but when I hit Enter, I get an error and H$7 is highlighted ("ctrl + shift + enter" doesn't help).

Here's an excerpt of the formula that works well for other queries on my worksheet:

=SUMPRODUCT(--(TEXT('Current update analysis'!$O$2:OFFSET('Current update analysis'!$O$2;(COUNTA('Current update analysis'!$B:$B)+20);"mm.yyyy")=TEXT({H$7;I$7;J$7};"mm.yyyy")); --('Current update analysis'!$k$2:OFFSET('Current update analysis'!$k$2;(COUNTA('Current update analysis'!$B:$B)+20)="ok"))

how I could/should structure the formula for it to work?

Filter Function Not Returning Correct Results In The Code?

Mar 20, 2013

In an excel sheet, I am using a macro to filter. Macro code is as follows. When I run this macro, it returns 4 rows matching the criteria from 560 rows in the excel sheet.

VB:
ActiveSheet.Range("$A$1:$I$566").AutoFilter Field:=1, Criteria1:= _
">=11/11/2012 22:13", Operator:=xlAnd, Criteria2:="<=11/12/2012 6:47"

I want to use the same criteria in the vb.net code, to do same thru vb.net. But, when I run the same code in vb.net, it just returns only 1 row (1st row only).

VB:
[FONT=Consolas][SIZE=2][COLOR=#0000ff]xlsRange1.AutoFilter(Field:=1, Criteria1:=">=11/11/2012 22:13", Operator:=Excel.XlAutoFilterOperator.xlAnd, Criteria1:="<=11/12/2012 6:47")

This returns 1 instead of 4 expected.
