Description

Normality Test function used to perform D'Agostino-K squared tests Analysis.

Syntax

int ocmath_k_squared_test( const double * pData, UINT nSize, NormTestResults2 * Chi2Res, NormTestResults2 * SkewRes, NormTestResults2 * KrutRes )

Parameters

pData: [input] Pointer of the dataset to analyse
nSize: [input] the number of the elements of the dataset
Chi2Res: [output] D Agostino's Chi2 test result
SkewRes: [output] Skewness test result
KrutRes: [output] Krutosis test result

Return

Returns STATS_ERROR_ARRAY_TOO_SMALL if the size of input array is too small or returns STATS_NO_ERROR on successful exit.

Examples

EX1

{
	vector vecData = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
	
	int nRet;	
	NormTestResults2 stChi2Res, stSkewRes, stKrutRes;	
	if( STATS_NO_ERROR == (nRet = ocmath_k_squared_test(vecData, vecData.GetSize(), &stChi2Res, &stSkewRes, &stKrutRes)) )
