Hello,
I want to estimate the exponential parameter by using optim with the following
input, where t contains 40% of the data and q contains 60% of the data within
an interval. In implementing the code command for optim i want it to contain
both the t and q data so i can obtain the correct estim

I have having the following error message when trying to optimize a function

Can someone tell me
