MLE_WL returns maximum likelihood estimates of parameters.
First, the estimate of phi is obtained from one dimensional non linear equation.
Then, by plugging in the estimated phi, the estimate of lambda is easily obtained.
Usage
MLE_WL(y, init)
Value
A numeric vector of MLE for lambda and phi.
Arguments
y
a numeric vector of observations.
init
a initial value for estimate phi.
Details
These functions implement formulas given in Hyoung-Moon Kim. et al. (2020).
