Dear all, I don't know what's my question is called. I have a performance variable A, such as sales. And I have another variable B, let's say establish time of firm. I want to create the third variable that is sales without the effect of establish time. Maybe it can be called partial effect problem. I'm not sure.
Does anyone have any suggestion? Thank you in advance! All the best, Wei-Wei ______________________________________________ [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
