Question

For this question use r studio r language!

1. The Gamma distribution is often used to describe the wait time until a certain number of events occurs.

Assume x1, . . . , xn ∼iid Gamma(α, β), where α is shape and β is rate. Calculate the maximum likelihood estimator of β either by hand or via R, but not both. The probability density function (PDF) for the Gamma distribution is:

 

Ba
f(r|a, B) =
-Bx
e
If you calculate by hand, your final answer should be B =
solution, you must provide a complete solution all the way down through optim(...),
assuming your data is stored in a variable generated through the following code:
data <- rgamma(n=1e5, shape=D3, rate=5)
If you provide R code as a
....
NOTE: If you use RStudio, you may not use dgamma() for your log-likelihood func-
tion! The Gamma function r(@) (not distribution, but function) is gamma() in
RStudio-try ?gamma for help using it.
