I am currently working on a statistical model. In order to estimate the parameters of model, I resorted to a stochastic version of the famous Expectation-Maximization algorithm. This stochastic approximation is the Monte Carlo Markov Chain Stochastic Approximation EM algorithm (MCMC-SAEM). I have already written the algorithm in Matlab but my code is not great because the algorithm runs very very slowly. I think that the code can easily be improved. I have tested my algorithm on simulated data (to see whether the algorithm allows to retrieve the parameters used to generate the data). The results obtained after after a few hundred iterations seem OK but I am not completely sure about that. It is just an impression for the moment. The job would consist in checking the existing code for mistakes and improving the code to obtain better runtime performances. As a consequence, the job requires a good knowledge and a good understanding of mathematical concepts and algorithms such as Monte ...

Hello, I need help with the MATLAB function I have. A few years ago someone programmed a function for me that calculates intersection points of various curves and then provides output. I recently tried to run the function, but it wouldn't work. Matlab gives an error message. Here is what I need. 1. Someone to look at the function and see what the problem is. Why the error message. 2. If the fix is easy, to fix it. 3. Answer 2-3 questions I might have. A knowledgeable person should get all of the above done in about 1 hour. That's what the project is for. IF the function requires more time to fix, well, we will add to the project and to the amount at $20/hour. As long as you provide me an estimate.
