Hi guys, Here I have a dataset with 800 positive samples and 800 negative ones looking like this
y x1 x2 1 0 1 -1 1 1 ...... I want to build a logistic regression model with y as the dependent variable, x1 and x2 as the independent variables (logit(y)=b0+ b1*x1 +b2*x2.). Then I want to compare this model with the NULL model which is b1=0 and b2=0 using a score test. With the P value I get from score test, I can then tell whether the two independent variables are significant related with y. Does anyone know how to do that in R? Which function should I use? Many many thanks, --Jerry [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
