Hi Thomas, these are relatively new options that haven't made it into the manual yet. Typically for linear regression you have independent x varaibles x_1,x_2,x_3,...,x_n and a single dependent varaible y. The default "multiple linear regression" considers a single linear model for all n+1 varibales (with the single y dependent, r response, varaible.) If you choose "multiple 2 variable regressions" considers n separate linear models, each for two variables, an independent x_i and dependent y. If you choose "multiple 2 variable regressions with multiple dependent variables", you need to specify a single independent variable x and multiple dependent variables y_1 to y_n, and separate linear models are considered, each for two variables, an independent x and dependent y_i. I hope this explains it. Andreas _______________________________________________ gnumeric-list mailing list gnumeric-list@gnome.org http://mail.gnome.org/mailman/listinfo/gnumeric-list
