The Frechet-Weibull Distribution

dfr_wei(x, fr_shape = 2, fr_scale = 100, wei_shape = 2,
  wei_scale = 1000, fr_weight = 0.5, log = FALSE)

qfr_wei(p, fr_shape = 2, fr_scale = 100, wei_shape = 2,
  wei_scale = 1000, fr_weight = 0.5, log = FALSE)

pfr_wei(q, fr_shape = 2, fr_scale = 100, wei_shape = 2,
  wei_scale = 1000, fr_weight = 0.5, log = FALSE)

Arguments

x

vector of quantiles
fr_shape

the Frechet shape
fr_scale

the Frechet scale
wei_shape

the Weibull shape
wei_scale

the Weibull scale
fr_weight

numeric value from 0 to 1, the Frechet weight, where the corresponding Weibull weight is (1 - fr_weight).
log

logical passed to actuar::dinvweibull, if TRUE probabilities/densities are returned as log(p).

Details

Density, distribution function, quantile function, and random generation for the combined Frechet-Weibull distribution with five parameters: fr_shape, fr_scale, wei_shape, wei_scale, and fr_weight.
