Description

Function to perform a One Sample t-Test.

Syntax

int ocmath_one_sample_t_test( const double * pData, UINT nSize, const HypotTestOptions * opt, tTestMean1SampleResults * res )

Parameters

pData: [Input] pointer to data points for One Sample t-Test
nSize: [Input] number of data points in pData
opt: [Input] structure containing t-Test options
res: [Output] structure containing t-Test Results

Return

Returns STATS_NO_ERROR on successful exit and a non-zero STATS error code on failure.

Examples
