Estimating the parameter of the Maxwell distribution by maximum likelihood estimation.
maxwell(link = "loglink", zero = NULL, parallel = FALSE,
type.fitted = c("mean", "percentiles", "Qlink"),
percentiles = 50)
Parameter link function applied to rate
.
See Links
for more choices and information;
a log link is the default because the parameter is positive.

See CommonVGAMffArguments
for information.
Using "Qlink"
is for quantile-links in VGAMextra.
An object of class "vglmff"
(see vglmff-class
).
The object is used by modelling functions such as vglm
,
rrvglm
and vgam
.
The Maxwell distribution, which is used in the area of
thermodynamics,
has a probability density function that can be written
