XLStat - ANCOVA (Analysis of Covariance)

XLSTAT enables you to perform one and multiple way ANCOVA. Up to order 4 interactions between factors can be included in the model. Order 2 interactions between factors and quantitative variables can be included in the model. Parameters, residuals analysis, Type I SS, Type III SS, and predictions are displayed.

Several multiple comparison methods can optionally be performed: Bonferroni's and Dunn-Sidak corrected t test, Tukey's HSD test, Fisher's LSD test, Duncan's test, Newman-Keuls' (SNK) method and the REGWQ method.

The Dunnett's test is available to allow users to perform multiple comparisons with control (MCC) and Multiple comparison with the best (MCB).
