I have some data to analyse and I am having trouble with the attached sheet.
There are 3 columns, SPDIFF, %VDU and SEA STATE. SPDIFF is the dependent variable and the other 2 are the independents
On the sheet, I done multiple regression using data in the CEDECKOFFS and got results shown in the CEDECKOFF1 tab. When I came back to it a few weeks later I done it again but got the results in CEDECKOFF2. They were done on 2 different PCs if that matters?
I cannot figure out why thee are different and now I am unsure which one is the correct one.
I'm trying to see if there is a relationship between 'SPDIFF' and '%VDU' usage, and was advised to include the 'SEASTATE' and use multiple regression.
Any info appreciated
