Regression Analysis and Applications


- A broad knowledge of linear regression analysis (simple and multiple) in the context of its application to health
- Interpretation and critical evaluation of empirical results
- Procedures and validation techniques of linear models
- Theoretical framework used in the empirical analysis of linear regression models, such as the properties of least squares estimators, maximum likelihood and hypothesis testing.

- Be a proficient user of the regression models applied to problems in health
- Perform statistical tests to ascertain the validity of the assumptions underlying the linear regression model.
- Build and interpret survival curves and respective hypothesis testing
- Being a critical reader of literature of linear regression models and survival analysis in health
