-------------------------------------------------------------------------
Description
discrim performs discriminant analysis, which is also known as
classification. kth-nearest-neighbor (KNN) discriminant analysis, linear
discriminant analysis (LDA), quadratic discriminant analysis (QDA), and
logistic discriminant analysis are available.
Examples
Setup
. webuse rootstock
Fit a kth-nearest-neighbor discriminant analysis model
. discrim knn y*, k(5) group(rootstock)
Fit a linear discriminant analysis (LDA) model with equal prior
probabilities for the six rootstock groups
. discrim lda y1 y2 y3 y4, group(rootstock)
Fit a quadratic discriminant analysis (QDA) model with prior
probabilities of 0.2 for the first four rootstocks and 0.1 for the last
two root stocks
. discrim qda y*, group(rootstock) priors(.2,.2,.2,.2,.1,.1)
Fit a logistic discriminant analysis model
. discrim logistic y*, group(rootstock)
