【Covariance_a】
- Inputs: IndArray[Xsize](NumericArrayRef), DepArray[Ysize](NumericArrayRef), ArraySize(Numeric);
- Variables: var0(0), var1(0), var2(0);
-
- condition1 = MinList(Xsize, Ysize, ArraySize) > 0 ;
- If condition1 Then Begin
- var0 = Average_a(IndArray, ArraySize);
- var1 = Average_a(DepArray, ArraySize);
- var2 = 0;
-
- For value1 = 1 To ArraySize Begin
- var2 = var2 + (IndArray[value1] - var0) * (DepArray[value1] - var1);
- End;
- Covariance_a = var2 / ArraySize;
- End
- Else
- Covariance_a = -1;
