ecd (version 0.9.2.4)

ecd: Constructor of ecd class

Description

Construct an ecd class by providing the required parameters. The default is the standard cusp distribution. Cusp is validated by eps = max(.Machine$double.eps*1000, 1e-28).

Usage

ecd(
  alpha = 0,
  gamma = 0,
  sigma = 1,
  beta = 0,
  mu = 0,
  cusp = 0,
  lambda = 3,
  with.stats = TRUE,
  with.quantile = FALSE,
  bare.bone = FALSE,
  verbose = FALSE
)

Arguments

alpha

numeric, the flatness parameter. Default: 0.

gamma

numeric, the sharpness parameter. Default: 0.

sigma

numeric, the scale parameter. Must be positive. Default: 1.

beta

numeric, the skewness parameter. Default: 0.

mu

numeric, the location parameter. Default: 0.

cusp

logical, indicate type of cusp. The singular points in cusp requires special handling. Default: 0, not a cusp. 1: cusp with alpha specified. 2: cusp with gamma specified.

lambda

numeric, the leading exponent for the special model. Default: 3.

with.stats

logical, also calculate statistics, default is TRUE.

with.quantile

logical, also calculate quantile data, default is FALSE.

bare.bone

logical, skip both const and stats calculation, default is FALSE. This for debug purpose for issues on integrating \(e^y(x)\).

verbose

logical, display timing information, for debugging purpose, default is FALSE.

Value

An object of ecd class

Examples

# NOT RUN {
d <- ecd()
d <- ecd(1,1)
d <- ecd(alpha=1, gamma=1)
# }
