Lack of independence in anova()
If the observations are normally distributed and the 2xk design is
balanced, theory requires that the tests for interaction and row effects be
independent. In my program, appended below, this would translate to cntT
(approx)= cntR*cntI/N if all R routines were functioning correctly. They
aren't.
sim2=function(size,N,p){
cntR=0
cntC=0
cntI=0
cntT=0
cntP=0
for(i in 1:N){

Subject: [R] How does the lm() function work?
Does the lm() function use forward, backward, stepwise or some other method
of multivariable regression? Where can I look up the details?
