Hello I am working on hedonic property value approach. I have four cross section units in my study. I want to pooled the data and then estimate a regression model in which I would have different intercepts and slopes for all the four cross sections. Actually I just only want a separate slope for one specific independent variable for all four cross sections. Can you help me how to make a model with different intercepts and slopes. And secondly how to make a spreadsheet.

EViews has a nice function called @expand for such purposes. For instance, the first specification below will produce a separate intercept for each categories, whereas the second one will take the first category as the reference group and measure the difference/effect of other categories.

@ trubador thanks for reply. It worked. Kindly tell me how to make a spreadsheet for that kind of analysis?????
