Statistical Methods in Public Health IV

1. Frame a scientific question about the dependence of a continuous, binary, count, or time-to-event response on explanatory variables in terms of linear, logistic, log-linear, or survival regression model whose parameters represent quantities of scientific interest
2. Design a tabular or graphical display of a dataset that makes apparent the association between explanatory variables and the response
3. Choose a specific linear, logistic, log-linear, or survival regression model appropriate to address a scientific question and correctly interpret the meaning of its parameters.
4. Appreciate that the interpretation of a particular multiple regression coefficient depends on which other explanatory variables are in the model
5. Estimate the unknown coefficients and their standard errors using maximum(or partial) likelihood and perform tests of relevant null hypotheses about the association with the response of particular subsets of explanatory variables
6. Check whether a model fits the data well; identify ways to improve a model when necessary
7. Use several models for the analysis of a dataset to effectively answer the main scientific questions
8. Describe how longitudinal data differ from cross-sectional data and why special regression methods are sometimes needed for their analysis
9. Summarize in a table, the results of linear, logistic, log-linear, and survival regressions and write a description of the statistical methods, results, and main findings for a scientific report
10. Perform data management, including input, editing, and merging of datasets, necessary to analyze data in Stata
11. Complete a data analysis project, including data analysis and a written summary in the form of a scientific paper
