I would really like to see a suite of data mining/machine learning analytic
tools, such as classification and regression trees, etc.

Subject: st: Features for Stata 14

Since it is still fairly early in the development cycle for the next release
of Stata, I thought it might be good to start a thread about things that
people would like to see added to the next release.  

I would definitely be interested in seeing some updates/expansions to the
graphics capabilities of Stata.  Alpha level blending is something that has
come up several times and adding interactive graphics would be a great
addition to the existing commands (e.g., functionality that is common in
Tableau and several packages in R).  

Documentation of the lower level graphics commands to make it easier for
users to extend the graphics capabilities.  

Latent Class Analysis and Latent Transition Analysis with support for all
types of manifest variables.

Multivariate mixed-effects models 

Exploratory Factor Analysis with nominal/ordinal/non-normal variables

Improved debugging tools (e.g., stepwise evaluator for programs, more
informative error messages, etc...)

New ways to generate samples of data with specified correlation
structures/distributions

I'm curious to see what other people have to say on this topic as well.

Billy
