Description

Survival Analysis function used to compute the statistics of survival function comparison. This is an OriginPro only function.

Syntax

int ocmath_surviv_fn_comp( const double * pTime, uint nTime, const double * pCensor, uint nCensor, const double * pFactor, uint nFactor, const double * pCensored, uint nCensoredVal, SFComp * psSFComp, int nMethod = 0 )

Parameters

pTime: [Input] pointer to time values
nTime: ]Input] size of time values.
pCensor: [Input] pointer to censor values
nCensor: [Input] size of censor values
pFactor: [Input] pointer to Factor value to indicates which group the observation belongs to.
nFactor: [Input] size of factor values
pCensored: [Input] pointer to Censored value. Please make sure that value of pCensored are all in pCensor and value are unduplicated.
nCensoredVal: Input size of censored values, which needs to be less than 20
psSFComp: [Ouput] pointer to structure containing test statistics of survival functions comparison
nMethod: [Input] flag to indicats method used in the compasiton; SA_SFCOMP_LOGRANK: Log rank; SA_SFCOMP_BRESLOW: Breslow; SA_SFCOMP_TARONEWARE: Tarone-Ware

Return

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