Log Hazard Function for a Generalized Weibull Process
Description
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
where is the scale parameter of the distribution,
is the shape, and
is the family
parameter.
gives a Weibull distribution, for
,
a generalized F distribution,
and for
,
a Burr type XII distribution.
