data analysis


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. descriptive descriptive and exploratory data analysis, hypothesis generating more than confirmatory analysis model validation model validation and interpretation bayes Bayesian data analysis, modeling, inference data reduction data reduction (principal components, etc.), clustering, unsupervised learning accuracy accuracy and information measures, discriminaton, calibration data problems statistical approaches dealing with missing data and measurement error formal statistical tests and inference models Formulation, parameter estimation, and interpretation of specific statistical models machine learning machine learning, exclusive of traditional statistical models 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 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)
