----- Message d'origine ---- De : Justin Rapp <[EMAIL PROTECTED]> À : [email protected] Envoyé le : Vendredi, 23 Juin 2006, 10h07mn 38s Objet : [R] Interpreting as.factor When I run a linear regression and include a variable in the regression with as.factor i.e. lm(y ~x +as.factor(x1) and i read the output as as.factor(x1)1.... as.factor(x1)2... etc. how do i interpret the estimate for each level? Is this simply to be regarded as a shift in the equation predicted by the intercept and independent variable x? jdr -- Justin Rapp 409 S. 22nd St. Apt. 1 Philadelphia, PA 19146 Cell:(267)252.0297 ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html [[alternative HTML version deleted]]
