- Calculating the coefficient of correlation
- Number of elements found in the matrix
- Error management
StatCorrelation (Function) Calculates the coefficient of correlation between two series of values.
ResCorrelationCoef = StatCorrelation("MyMatrix", 1, 2, False)
Sintaxis
<Result> = StatCorrelation(<Matrix> [, <1st row/1st column> [, <2nd row/2nd column> [, <Row/Column>]]])
<Result>: Real - Coefficient of correlation that exist between the two series of values,
- 0 if the coefficient of correlation is null.
<Matrix>: Character string Name of the matrix containing the data, defined by MatCreate. <1st row/1st column>: Optional integer 1st row or 1st column containing the data (1 by default). <2nd row/2nd column>: Optional integer 2nd row or 2nd column containing the data (2 by default). <Row/Column>: Optional boolean - True (by default) if the series of values correspond to matrix columns,
- False if the series of values correspond to matrix rows.
Observaciones Calculating the coefficient of correlation  StatCorrelation("MyMatrix", 1, 3, False) returns 0,997054.  StatCorrelation("MyMatrix", 1, 3, False) returns 1.  StatCorrelation("MyMatrix", 1, 3, False) returns 0. Number of elements found in the matrix The number of elements found in the matrix is taken as reference. This number of elements corresponds to: - the number of matrix rows, returned by MatNbLine.
- the number of matrix columns, returned by MatNbColumn.
If the series contain less elements than the matrix, the missing values are automatically filled with 0. These values are taken into account during the calculations. Caution: StatCorrelation returns no error code. To find out whether errors have been generated when calculating the coefficient of correlation, use StatError. To get more details on the error, use ErrorInfo with the errMessage constant. Clasificación Lógica de negocio / UI: Código neutro
