My name is Julia and I'm doing my phd on roc analysis.
I'm trying to write a maximization function for the likelihood attached in
For some reason it's not working I keep getting \this error:
Error: unexpected symbol in:
Error: unexpected '}' in "}"
Error in optim(c(meany0, meany1, stdy0, stdy1, dx, V, d), logl) :
function cannot be evaluated at initial parameters
This is what I wrote
# maximizing the log likelihood function
Need help please.
