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.
dweibull for the Weibull distribution,
df for the F distribution,
dburr for the Burr distribution.dgweibull(5, 1, 3, 2) pgweibull(5, 1, 3, 2)
