I'm having some difficulties with applying a multivariate linear regression.
I want to predict the Log D, which in this case is defined by the following function:
Log D = a (constant) + b*fo2 + c*NBO/t + d*(1/T) + e*(P/t) + f*(LN-1-Xs)
So, D is predicted by a number of variables.
If I want to regress D, where can I enter the formula to which the multivariate linear regression needs to comply?
In the menu, I can only add either the variables as dependent variables, covariates or fixed. None of them are fixed, but all are dependent variables and covariates.
Where should I put Log D then?
Kind regards from Holland,
