Hi,I am trying to use the anova command but I am not sure I am doingthe right thing.I have a dependent variable Y which I explain by 10 explanatoryvariables, half of which are categorical while the others arecontinuous.When I use the anova command and specify which variables arecontinuous, then I get a table with the Partial SS for each of theexplanatory variables.If I sum the Partial SS for all variables then this is much smallerthan the value reported for the Model SS. How is that the case? Whatam I missing here?What I want to is to find to what extent each of the differentexplanatory variables explains the variance of the dependentvariable, which should be given by the ratio between the Partial SSof each variable and the total SS. Am I right?Many thanks! Alice. * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
