This course covers key areas of statistical computing including:

1. Generalized linear models
   • Logistic and Poisson regression models
   • Generalized linear models, the general case
   • Linear models of variance and covariance analysis
   • Log-linear models
2. Time series analysis
   • Stochastic processes
   • Autocovariance and autocorrelation
   • Stationary time series
   • Autoregressive processes
   • Moving average processes
   • ARMA processes
   • Spectral analysis of time series
3. Computational intensive estimation methods
   • EM algorithm
   • MCMC algorithms
   • Bootstrap
4. Model evaluation and selection in regression analysis
   • Criteria for evaluating and selecting the appropriate model
   • Prediction error estimation: Cross-validation
   • Model selection methods: Stepwise methods, AIC, BIC
   • Variable selection methods: Regularization, Ridge,
     LARS, LASSO
5. Data imputation methods
   • Methods based on regression and covariance analysis.
   • Methods based on the EM algorithm
