y
| vector of responses. |
q
| vector of quantiles. |
m
| vector of location parameters. |
s
| vector of dispersion parameters. |
f
| vector of family parameters. |
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.
