Description

Estimate parameters for 3-paramete Weibull distribution

Syntax

int ocmath_para_wbl3( int iSize, const double * pData, double alpha, double * pPara, const double * pdFixed = NULL, double * pCov = NULL, double * pSE = NULL, double * pCI = NULL, double * pAD = NULL, double * pPval = NULL, int nPercents = 0, const double * pPercents = NULL, double * pPercentiles = NULL, double * pLower = NULL, double * pUpper = NULL, double * pLogLikelihood = NULL )

Parameters

iSize: [input]input data size
pData: [input]input data
alpha: [input]alpha value
pPara: [output]shape, scale and threshold parameter
pdFixed: [input]Fixed parameter value or missing value if not fixed
pCov: [output]covariance
pSE: [output]Standard error of mean
pCI: [output]confidence interval
pAD: [output]Anderson-Darling statistic
pPval: [output]P-value
nPercents: [input]number of Percents
pPercents: [input] Percents
pPercentiles: [output] Percentiles
pLower: [output] lower confidence
pUpper: [output] upper confidence
pLogLikelihood: [output] logLike value

Return

return 0 on successful exit; if an error or warning has been detected, then it returns the specific error or warning code.
