The complementary Bell extended exponential distribution {BGFD}

The complementary Bell extended exponential distribution

Description

Density, probability, quantile function, random generation, survival function, hazard rate function and maximum likelihood estimates from the complementary Bell extended exponential distribution.

Usage

dCBellEE(x, alpha, beta, lambda, log = FALSE)
pCBellEE(x, alpha, beta, lambda, log.p = FALSE, lower.tail = TRUE)
qCBellEE(p, alpha, beta, lambda, log.p = FALSE, lower.tail = TRUE)
rCBellEE(n, alpha, beta, lambda)
sCBellEE(x, alpha, beta, lambda, log.p = FALSE, lower.tail = TRUE)
hCBellEE(x, alpha, beta, lambda, log = FALSE,log.p = FALSE, lower.tail = TRUE)
mCBellEE(x, alpha, beta, lambda, method="B")

Arguments

x

A vector of (non-negative integer) quantiles.

p

A vector of probablities.

n

The number of random values to be generated under the complementary Bell extended exponential distribution.

lambda

The strictly positive parameter of the Bell distribution (\lambda > 0).

alpha

The strictly positive scale parameter of the baseline extended exponential distribution (\alpha > 0).

beta

The strictly positive shape parameter of the baseline extended exponential distribution (\beta > 0).

lower.tail

if FALSE then 1-F(x) are returned and quantiles are computed 1-p.

log

if TRUE, probabilities p are given as log(p).

log.p

if TRUE, probabilities p are given for exp(p).

method

the procedure for optimizing the log-likelihood function after setting the intial values of the parameters and data values for which the complementary Bell extended exponential distribution is fitted. It could be "Nelder-Mead", "BFGS", "CG", "L-BFGS-B", or "SANN". "BFGS" is set as the default.

Details

The functions allow fitting the complementary Bell extended exponential distribution and evaluating the probability density function, cumulative distribution function, quantile function, random numbers, survival function, hazard rate function, and maximum likelihood estimates (MLEs) of the unknown parameters with standard error (SE) of the estimates. It also provides the goodness-of-fit measures such as the Akaike Information Criterion (AIC), Bayesian Information Criterion (BIC), the minimum value of the negative log-likelihood function, Anderson-Darling (A) test, Cramer-Von-Mises (W) test, Kolmogorov-Smirnov test, P-value and convergence status.

Value

dCBellEE gives the (log) probability function. pCBellEE gives the (log) distribution function. qCBellEE gives the quantile function. rCBellEE generates random values. sCBellEE gives the survival function. hCBellEE gives the hazard rate function. mCBellEE gives the estimated parameters along with SE and goodness-of-fit measures.
