Hi:
Is equation written as a function? As in, say,
eq <- function(k) 1/LR - (exp(-k * T) * LM) * (1 - exp(-k))
I believe the log of the likelihood would be a simpler expression to
maximize...

I am trying to figure out how
I am trying to figure out how to run maximum likelihood in R. Here is my
situation:
I have the following equation:
equation<-(1/LR-(exp(-k*T)*LM)*(1-exp(-k)))
LR, T, and LM are vectors of data. I want to R to change the value of k
to maximize the value of equation.
