Sorry there was a mistake: Hi R users I want to do a multiple linear regression with R With a normal model (Y=Cste+A1*X1+A2*X2) the program would be lm(Y~X1+X2) My model is Y=Cste+A1*X1+A2*X2 with the constraint A1=-A2 What is the program for such a model? Best regards -- View this message

Hi R users I want to do a multiple linear regression with R With a normal model (Y=Cste+A1*X1+A2*X2) the program would be lm(Y ~X2+X2) My model is Y=Cste+A1*X1+A2*X2 with the constraint A1=-A2 What is the program for such a model? Best regards -- View this message in context: http://old.na
