Description

Performs the Frieman two-way analysis of variance. The main engine is nag_friedman_test(g08aec). This is an OriginPro only function.

Syntax

int ocmath_friedman_test( const double * pData, const uint nSize, const double * dpTreaments, const uint nTreatmSize, const double * dpBlocks, const uint nBlockSize, NPHSummary * FriSummary, NPHRanks * FriRanks, NPHStats * FriStats )

Parameters

pData: [input] pointer to data points
nSize: [input] size of pData
dpTreaments: [input] pointer to integer treaments
nTreatmSize: [input] size of dpTreaments, it should equal to nSize
dpBlocks: [input] pointer to integer blocks.
nBlockSize: [input] size of dpBlocks. it should equal to nSize
FriSummary: [output] pointer to structure containing summary statistics of each groups; KruSummary[i-1]: Summary statistics of i-th group
FriRanks: [output] pointer to structure containing Statistics of Ranks; FriRanks[i-1]: Ranks of i-th group
FriStats: [output] pointer to structure containing the test statistic and p-value, No corrected for ties.

Return

Returns STATS_NO_ERROR on successful exit or an STATS error code on failure.
