dhjorth(y, m, s, f) phjorth(q, m, s, f) hhjorth(y, m, s, f)
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
.
dhjorth
gives the density, phjorth
gives the distribution
function, hhjorth
gives the hazard function.
The Hjorth distribution has density
f(y) = (1+s y)^(-f/s) exp(-(y/m)^2/2) (y/m^2+f/(1+s y))
where m is the location parameter of the distribution, s is the dispersion, and f is the family parameter.
