| Generalized Weibull(rmutil) | R Documentation |
These functions provide information about the generalized Weibull
distribution with location parameter equal to m, dispersion equal
to s, and family parameter equal to f.
dgweibull gives the density, pgweibull gives the distribution
function, hgweibull gives the hazard function.
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 location parameter of the distribution, s is the dispersion, and f is the family parameter.
f=infinity gives a Weibull distribution, for s=1, f<0 a generalized F distribution, and for s>0, f<0 a Burr type XII distribution.
