multiple regression formula

Postby SimonJulAndreasen » Wed Mar 21, 2012 10:48 am

Hey folks

I am currently working on a school project with multiple regression analysis on a timestudy
where the dependen variable are the porduction time. and then i have about 25 indepndents variable to estimate the production time.

The R square value are 0,720 which is accapteable?

But i need to construct the formula so i can use the analysis that spss have made for me. The will make me able to predict the production time on comming orderes. But im not sure how i shuld construct the formula so i will end up with a time for production. my spss results are attached can someone help me in cunstruting that formula?

Best regards

That information is contained in your output model table which shows, among other things, the beta coefficients

What version of SPSS are you running
See the note below

Hi, Could I bump this? I'm wondering what is the equation for the model. So based on my logistic regression, I found three independent variables which can be used to predict my dependent variable. If I know the value for these three ind. variables in the future, what equation would I plug them into in order to predict my dependent variable? Thanks so much
