I am using discrim command for discrimination analysis in STATA 11. I
am interested in leave-one-out classification tables. For linear,
quadratic, or knn discriminant analysis one can achieve this by typing
respectively
discrim lda ... , ... nootable lootable
discrim qda ..., ... nootable lootable
discrim knn ...., ... nootable lootable
or by using
estat classtable, loo
after performing the discrim commands respectively. This is discussed
nicely in the STATA 11 manual.
However, for logistic discriminant analysis, the STATA 11 manual does
not discuss lootable or loo. In fact, if one types
discrim logstic ...., lootable notable
one obtains an error message
option lootable not allowed
r(198);
A similar error message occurs after
discrim logistic ..., ...
estat classtable, loo
Why is leave-one-out not allowed in logistic discriminant analysis?
Does anyone know a way around this problem?
Thank you.
