TMtxAnova.Replications Property

Number of observations per data matrix "cell".

Pascal

property Replications: Integer;

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).

Example

Note that Data.Rows mod 3 = 0 !!

MtxAnova1.Data.SetIt(6,2,false,[1,2,
                              2,3,
                              5,7,
                              12,1,
                              5,8,
                              3,8]);
MtxAnova1.IsAnova1 := false; // do two-way ANOVA
MtxAnova1.Replications := 3; // three rows per "group"
MtxAnova1.ResultDest := StringGrid1;
MtxAnova1.Recalc;

MtxAnova1->Data->SetIt(6,2,false,OPENARRAY(double,(1,2,
                              2,3,
                              5,7,
                              12,1,
                              5,8,
                              3,8)));
MtxAnova1->IsAnova1 = false; // do two-way ANOVA
MtxAnova1->Replications = 3; // three rows per "group"
MtxAnova1->ResultDest = StringGrid1;
MtxAnova1->Recalc();
