Dear R-project
I could not validate one logistic model because when I used the function
lrm.fit of the package rms the program showed a error message. It said that
the variable Clam and offset must have same length.
ext <- lrm.fit( ,Clam, offset="X")
In this case, Clam is variable depend or variable that we want to
predictive and X is linear predictor of the other logistic model.
We want to evaluate a logistic model in new data set. However, we don't
have the development data set of logistic model, only we have the equation.
We are using the function lrm.fit because it allows to use offset.
What do you recommend me?
Thank you member of R-project
