The Power Reversal Student t Distribution
Description
Density, distribution function, quantile function and random generation for the power reversal Student t distribution with parameters mu, sigma, lambda and df.
Usage
drpt(x, lambda = 1, mu = 0, sigma = 1, df, log = FALSE)
prpt(q, lambda = 1, mu = 0, sigma = 1, df, lower.tail = TRUE,
log.p = FALSE)
qrpt(p, lambda = 1, mu = 0, sigma = 1, df, lower.tail = TRUE,
log.p = FALSE)
rrpt(n, lambda = 1, mu = 0, sigma = 1, df)
Arguments
x , q |
vector of quantiles. |
lambda |
shape parameter. |
mu , sigma |
location and scale parameters. |
df |
degrees of freedom (> 0, maybe non-integer). df = Inf is allowed. |
log , log.p |
logical; if TRUE, probabilities p are given as log(p). |
lower.tail |
logical; if TRUE (default), probabilities are |
p |
vector of probabilities. |
n |
number of observations. |
Details
The reversal power Student t distribution has density
,
where is the location paramether,
the scale parameter and
the shape parameter.
