Description Usage Arguments Author(s) See Also Examples

These functions provide information about the generalized Weibull
distribution, also called the exponentiated Weibull, with scale
parameter equal to `m`

, shape equal to `s`

, and family
parameter equal to `f`

: log hazard.
(See 'rmutil' for the d/p/q/r boxcox functions density,
cumulative distribution, quantiles, and random generation).

The generalized Weibull distribution has density

*
f(y) = s f y^(s-1) (1-exp(-(y/m)^s))^(f-1) exp(-(y/m)^s)/m^s*

where *m* is the scale parameter of the distribution,
*s* is the shape, and *f* is the family
parameter.

*f=1* gives a Weibull distribution, for
*s=1*, *f<0* a generalized F distribution,
and for *s>0*, *f<=0* a Burr type XII distribution.
