LinStats is a collection of classes, functions and data that are useful for representing, solving and analyzing linear statistical models. LinStats has been updated to use a new object based approach to support incremental model-building and more sophisticated analysis.
Notably this is the first Matlab statistical package that can handle ANOVA and Variance Components models with fixed and random effects using Restricted Estimated Maximum Likelihood (REML) including the modern corrections for small sample size. This allows improved estimates for both fixed (Best linear unbiased estimates) and random terms (Best linear unbiased predictors).
Many statistical analysis including ANOVA involve random factors which poses challenging problems. Old solutions used approximations that were required before the advent of computers. Modern solutions use Restricted Estimated Maximum Likelihood. More recent enhancements and refinements include corrections for small sample size (Kenward and Roger) and take into account the uncertainty that parameter estimates have on variance estimates (Harville and Kackar).
This approach is becoming more common but the calculations are complex and this has slowed implementation. Matlab and R, for example, do not support this. I have only seen it in Professional statistics programs like SAS/JMP. Now, for the first time, Matlab Stats users don't need to take a backseat to users of those languages (at least in terms of mixed model analysis of linear models).
Fixed effects analysis outputs have been validated using National Institute of Standards and Technology Standards Technology Reference most difficult datasets (included with Linstats). Random effects outputs have been checked against results produced by SAS/JMP.
