Hi:
There are a couple of things here. Firstly, if you intend to predict from a
model in R, make sure your input to the model is a data frame. You can fit a
model piecemeal with a set of vectors, but there's a distinct possibility
you'll end up frustrated when trying to make predictions with new d
Hi,
I don't know how to make prediction with a factor in the linear model.
Say
yd=c(1,2,3,4,5)
> sl=c(2,3,4,5,6)
> sex=c("male","male","female","female","male")
> sex=factor(sex)
> m=lm(sl~yd+sex+sex:yd)
How to make a prediction with new data like yd=c(4,5,6,7,8) for male and
female s
