Trend function in excel
Hello.
I am working on a spreadsheet to forecast billing for next financial year. My spreadsheet is set up as follows:
List of clients in column A (i.e. client on each row from 1 to 200) and financial years as column heads from B (2021) to F (2025)
In column F I an extrapolating data using the trend function from the data in columns B to E.
Where there has been a decline in sales for any particular customer, the trend function is returning a negative amount in column F.
How do I input this formula so that any row which would return a negative number instead returns "0"?
I think this should be done by embedding the trend formula inside an if formula, but i cannot seem to get that right. The box either reads as "false" or the problem with formula box pops up.
RE: Trend function in excel
Hi Uday,
Thank you for the forum question.
As I understand it you work with one independent variable and one dependent variable. Normally the TREND function is used for linear regression with multiple independent variable.
The issue with the TREND function and why you cannot just use an IF is that the TREND function is an array function.
Please copy your TREND function in F2 and paste the function here in the forum. Then I will convert it to do what you want.
Kind regards
