data analysis


descriptive descriptive and exploratory data analysis, hypothesis generating more than confirmatory analysis data problems statistical approaches dealing with missing data and measurement error models Formulation, parameter estimation, and interpretation of specific statistical models model validation model validation and interpretation data reduction data reduction (principal components, etc.), clustering, unsupervised learning accuracy accuracy and information measures, discriminaton, calibration bayes Bayesian data analysis, modeling, inference uncertainty Quantifying uncertainty, displaying uncertainty, estimation of uncertainty, incorporation of uncertainty into decision making, etc. This includes but is not limited to confidence intervals, standard errors, Bayesian credible intervals, and sources of uncertainty. formal statistical tests and inference probability Probability theory, meaning, and application exclusive of statistical tests, etc. generalizability Generalizability of studies and statistical inferences, sample representativeness, target population comparative methods comparative performance of statistical analysis methods and predictive modeling approaches machine learning machine learning, exclusive of traditional statistical models variable selection Selection of predictive features in multivariable modeling, one-at-a-time screening of variables, and the cost of feature selection compared to using fuller models, possibly with penalization (shrinkage; regularization). causal inference Methods and approaches to causal inference modeling strategy General model specification issues, nonlinearities, interactions and heterogeneity of treatment effect, avoiding categorization, how to sequence multiple steps (which may involve multiple imputation and data reduction)
