multiTree is a java-based computer program for the analysis of multinomial processing tree models. Among other things, multiTree provides parameter estimation, hypothesis testing, checks for identifiability, bootstrapping, and power analysis. For download and additional information, see
For details, see:

If you prefer to use multiTree in the R environment, you may use the corresponding R interface. The multiTreeR package is available at github.
Lower bound N for FIA
The Fisher information approximation (FIA) of the normalized maximum likelihood is a model selection criterion based on the minimum description length principle. FIA should only be used if the total number of observations exceeds a lower bound. This Excel sheet computes this lower-bound N in contexts with multiple candidate models, to be used in conjunction with a suitable MPT modeling software such as multiTree. Get the Excel-Sheet here.

NOTAMO is an R package that estimates the parameters of a quantile mixture cumulative distribution function to comply with prespecified central moments. The quantile mixture can be used with the NORTA algorithm to generate multivariate non-normally distruted samples with given covariance matrix and central moments. NOTAMO can be downloaded from github. For details, see

NNNLSEM generates non-normal data with given moments using a structural model with non-linear linking functions. Get the MATLAB script here. For details, see
