Dear Forum,
I would need to write a function to calculate the cumulative distribution
function (cdf) of the gamma random variable. I am allowed to use the
following precoded functions: rgamma, pgamma, and dgamma. I am a little
overwhelmed by this project, I am wondering how I should start. Should I
sum dgamma (or pgamma) from 0 to x, in order to obtain the cdf at x?
Thanks in advance for your input.
