| Subject | st: STATA 11 discrim logistic leave-one-out |
| Date | Wed, 31 Mar 2010 14:13:56 -0700 |
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. -- ---------------------------------------------------------- Burkhard C.
