Density, distribution function, quantile function and random generation for the Flipped Gamma distribution,
a Gamma distribution reflected across the Y-axis. shape, rate and other parameters are inherited from the stats package.
One additional parameter, offset is provided to generate Flipped Gamma distributions with non-zero right endpoints, ending
at the offset value.
Usage
dgamma_flip(x, shape, rate = 1, offset = 0, ...)
pgamma_flip(q, shape, rate = 1, offset = 0, lower.tail = TRUE, ...)
rgamma_flip(n, shape, rate = 1, offset = 0, ...)
qgamma_flip(p, shape, rate = 1, offset = 0, lower.tail = TRUE, ...)Arguments
- x
numeric vector of quantiles
- shape
shape parameter of gamma distribution
- rate
rate parameter of gamma distribution, default 1
- offset
offset of the right end of the distribution
- ...
additional parameters to be passed to stats::dgamma, stats::pgamma, stats::rgamma and stats::qgamma
- q
numeric vector of quantiles
- lower.tail
logical; if TRUE (default), probabilities are \(P[X \le x]\), otherwise, \(P[X > x]\).
- n
number of observations
- p
vector of probabilities
