Distributions() R function from [greybox]

Distribution functions of the greybox package

The greybox package implements several distribution functions. In this document, I list the main functions and provide links to related resources.

Generalised normal distribution (with a kurtosis parameter by Nadarajah, 2005): qgnorm , dgnorm , pgnorm , rgnorm .
S distribution (a special case of Generalised Normal with shape=0.5): qs , ds , ps , rs .
Laplace distribution (special case of Generalised Normal with shape=1): qlaplace , dlaplace , plaplace , rlaplace .
Asymmetric Laplace distribution (Yu & Zhang, 2005): qalaplace , dalaplace , palaplace , ralaplace .
Logit Normal distribution (Mead, 1965): qlogitnorm , dlogitnorm , plogitnorm , rlogitnorm .
Box-Cox Normal distribution (Box & Cox, 1964): qbcnorm , dbcnorm , pbcnorm , rbcnorm .
Folded Normal distribution: qfnorm , dfnorm , pfnorm , rfnorm .
Rectified Normal distribution: qrectnorm , drectnorm , prectnorm , rrectnorm .
Three parameter Log Normal distribution (Sangal & Biswas, 1970): qtplnorm , dtplnorm , ptplnorm , rtplnorm .
