maximum likelihood with constraints in R
Hi R-experts,
There is lots of information about maximum likelihood estimation in R.
However, I didn't came across anything about maximum likelihood with constraints.
For example, estimation of parameters k(1) to k(20) with maximum likelihood, where sum(k(i)) = 0.
Is there any standard function in R that can do this, or is this something that I should set up myself?
Greetings,
Church

How to define proper breaks in RFM analysis
Hi
Your statement about attaching data is problematic. We cannot do much with it. Instead use output from dput(yourdata) to show us what exactly your data look like.
We also do not know how do you want to split your data. It would be nice if you can show also what should be the bins with respective data. Unless you provide this information you probably would not get any sensible answer.
Cheers

How to define proper breaks in RFM analysis
Hello,
I'm working on RFM analysis and i wanted to define my own breaks but my
frequency distribution is not normally distributed so when I'm using
quartile its not giving the optimal results.
so I'm looking for a better approach where i can define breaks dynamically
because after visualization i can do it easily but i want to apply this
model so that it can automatically define the
