ecd (version 0.9.2.4)

ecd.cusp: Cusp constructor of ecd class

Description

Construct an ecd class for cusp distribution by specifying either alpha or gamma, but not both. At the moment, it can't handle beta.

Usage

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

Arguments

alpha

numeric, the flatness parameter. Default: NaN.

gamma

numeric, the sharpness parameter. Default: NaN.

sigma

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

mu

numeric, the location parameter. Default: 0.

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

The ecd class

Examples

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