Linear, Multiplicative and Attraction models regression
Posted: Fri Aug 14, 2015 8:04 pm
Hello there!
I am trying to perform a market share value model which uses the following regressions (attached below). The problem i have is that for the multiplicative and attraction model the error term \epsilon_{j,t} is multiplying the equations. is there a way to performs these models?
Thanks in advice.
