computational_stats_MSc

This is a repo for graduate Computational Statistics problem sets and class information/data.

It includes my codes for topics as:

  • Fitting k-means clustering by minimizing variance/objective function
  • General Stats Optimization topics such as maximization of different likelihood functions: non-linear, constrained, block relaxtion ones, etc
  • Expectation Maximization Algorithm for a mixture of Multivariate Gaussians
  • Bootstrap and Permutation for linear regression and other problems
  • Monte Carlo methods and Importance Sampling
  • Markov-Chain Monte Carlo for bayesian stats: Metropolis-Hastings and Gibbs-Sampler for bayesian regression
  • Hidden Markov Chains applied to finance
  • Some linear algebra topics
  • Course Final Work: I've used a Sequential Quadratic Programming (SQP) method for optimizing mixture copula parameters instead of classical EM algos. To assess performance I've conducted a Monte Carlo expectation and s.d. estimation of a simulated mixture. Used the proposed optimization method to a financial portfolio optimization problem.
