TMtxAnova.Replications Property

Summary

Number of observations per data matrix "cell".

Declaration

Property Replications: Integer read FReplications write SetReplications default 1;

Description

Defines the number of observations per Data matrix "cell", where each cell includes Replications number of rows. For example, if Data has 6 rows and Replications is 2, then the "row" factor has 6/2 = 3 levels (1st level row 0..1, 2nd level row 2..3, 3rd level row 4..5). An exception is raised if A.Rows mod Replications is not zero (if A.Rows/Replications is not an integer). The Replications factor is taken into the account ONLY if IsAnova1 is false (two-way ANOVA).

Note that Data.Rows mod 3 = 0 !!
