Distributions pqdr wrapper

Description

Density, distribution, quantile function and random number generation for all the distributions in the package.

Usage

ddist(
  distribution = "norm",
  x,
  mu = 0,
  sigma = 1,
  skew = 1,
  shape = 5,
  lambda = -0.5,
  log = FALSE
)

pdist(
  distribution = "norm",
  q,
  mu = 0,
  sigma = 1,
  skew = 1,
  shape = 5,
  lambda = -0.5,
  lower_tail = TRUE,
  log = FALSE
)

qdist(
  distribution = "norm",
  p,
  mu = 0,
  sigma = 1,
  skew = 1,
  shape = 5,
  lambda = -0.5,
  lower_tail = TRUE,
  log = FALSE
)

rdist(
  distribution = "norm",
  n,
  mu = 0,
  sigma = 1,
  skew = 1,
  shape = 5,
  lambda = -0.5
)

Arguments

distribution	a valid distribution.
x, q	vector of quantiles.
mu	mean.
sigma	standard deviation.
skew	skew parameter.
shape	shape parameter.
lambda	additional shape parameter for the Generalized Hyperbolic distribution.
log	(logical) if TRUE, probabilities p are given as log(p).
lower_tail	if TRUE (default), probabilities are P[X \le x] otherwise, P[X > x].
p	vector of probabilities.
n	number of observations.

Value

d gives the density, p gives the distribution function, q gives the quantile function and r generates random deviates. Output depends on x or q length, or n for the random number generator.
