Examples

##
library(alr3)
data(landrent)
attach(landrent)
resp <- I(Y/X1)
y1 <-  split(resp, X4)$"1"
x21 <-  split(X2, X4)$"1"

##Fixed Precision
fit0 <- gamlss(y1 ~ x21, family=RBS(mu.link="identity"),method=CG()  )
plot(fitted(fit0),residuals(fit0),xlab="fitted values",ylab="Deviance")
##Varying Precision
fit1 <- gamlss(y1 ~ x21,sigma.formula = y1 ~x21, family=RBS(mu.link="identity",sigma.link="sqrt"),method=CG()  )
plot(fitted(fit1),residuals(fit1),xlab="fitted values",ylab="Deviance")
