The Ristic-Balakrishnan Odd log-logistic family of distributions (RBOLL-G)
Description
Computes the pdf, cdf, hdf, quantile and random numbers of the beta extended distribution due to Esmaeili et al. (2020) specified by the pdf
f=\frac{\alpha\,g\,G^{\alpha-1}\bar{G}^{\alpha-1}}{\Gamma(\beta)[G^\alpha+\bar{G}^\alpha]^2}\,\{-\log[\frac{G^\alpha}{G^\alpha+\bar{G}^\alpha}]\}^{\beta-1}
for G
any valid continuous cdf , \bar{G}=1-G
, g
the corresponding pdf, \Gamma(\beta)
the Gamma funcion, \alpha > 0
, the first shape parameter, and \beta > 0
, the second shape parameter.
Usage
prbollg(x, alpha = 1, beta = 1, G = pnorm, ...)
drbollg(x, alpha = 1, beta = 1, G = pnorm, ...)
qrbollg(q, alpha = 1, beta = 1, G = pnorm, ...)
rrbollg(n, alpha = 1, beta = 1, G = pnorm, ...)
hrbollg(x, alpha = 1, beta = 1, G = pnorm, ...)
Arguments
x |
scaler or vector of values at which the pdf or cdf needs to be computed. |
alpha |
the value of the first shape parameter, must be positive, the default is 1. |
beta |
the value of the second shape parameter, must be positive, the default is 1. |
G |
A baseline continuous cdf. |
... |
The baseline cdf parameters. |
q |
scaler or vector of probabilities at which the quantile needs to be computed. |
n |
number of random numbers to be generated. |
Value
prbollg
gives the distribution function,
drbollg
gives the density,
qrbollg
gives the quantile function,
hrbollg
gives the hazard function and
rrbollg
generates random variables from the The Ristic-Balakrishnan Odd log-logistic family of
distributions (RBOLL-G) for baseline cdf G.
