- Readings, plus an exercise on rational inattention
- An R file that calculates the objective function for the exercise is here. This file computes analytic derivatives
as well as the function value. The objective function is really badly behaved if some elements of the solution distribution are zero. So start by constraining
some rows of the matrix of joint probabilities of x and y to be zero, e.g. use only x=2,3,4 or x=1, 3, 5. Then, if now row is zero in the solution, the penalty
function part of the objective is not invoked near the solution. If you are writing your own code (e.g. in matlab), you might not need the analytic derivatives if
you avoid trying to find solutions in which some elements of the marginal density for x are zero. This R code works correctly with csminwelNew.R, csminit.R, and bfgsi.R
