common-arguments {LambertW}

Common arguments for several functions

Description

Reference list of most common function arguments in this package.

Arguments

y

a numeric vector of real values (the observed data).

distname

character; name of input distribution; see get_distnames.

type

type of Lambert W \times F distribution: skewed "s"; heavy-tail "h"; or skewed heavy-tail "hh".

theta

list; a (possibly incomplete) list of parameters alpha, beta, gamma, delta. complete_theta fills in default values for missing entries.

beta

numeric vector (deprecated); parameter \boldsymbol \beta of the input distribution. See check_beta on how to specify beta for each distribution.

gamma

scalar (deprecated); skewness parameter; default: 0.

delta

scalar or vector (length 2) (deprecated); heavy-tail parameter(s); default: 0.

alpha

scalar or vector (length 2) (deprecated); heavy tail exponent(s); default: 1.

tau

named vector \tau which defines the variable transformation. Must have at least 'mu_x' and 'sigma_x' element; see complete_tau for details.

return.u

logical; if TRUE, it returns the standardized input that corresponds to U, which is the zero-mean and/or unit-variance version of input X \sim F_X.

use.mean.variance

logical; if TRUE it uses mean and variance implied by \boldsymbol \beta to do the transformation (Goerg 2011). If FALSE, it uses the alternative definition from Goerg (2016) with location and scale parameter.
