LIN | R Documentation |
The function LIN()
defines the Lindley distribution with only one parameter
for a gamlss.family
object to be used in GAMLSS fitting
using the function gamlss()
.
LIN(mu.link = "log")
mu.link |
defines the mu.link, with "log" link as the default for the mu parameter. |
The Lindley with parameter mu
has density given by
f(x) = \frac{μ^2}{μ+1} (1+x) \exp(-μ x),
for x > 0 and μ > 0.
Returns a gamlss.family object which can be used to fit a LIN distribution in the gamlss()
function.
