Estimates the (1-parameter) Lindley distribution by maximum likelihood estimation.
lindley(link = "loglink", itheta = NULL, zero = NULL)
Link function applied to the (positive) parameter.
See Links
for more choices.
See CommonVGAMffArguments
for information.
An object of class "vglmff"
(see vglmff-class
).
The object is used by modelling functions such as vglm
and vgam
.
The density function is given by
