Linear Correlation and Regression
When conducting a radiologic research study on a sample of patients or healthy volunteers, a database to collect the data needs to be built. These data may be of various types (patient history, clinics, radiology, histopathology, etc.). In practice, we obtain the information thought to be useful to the research study for each enrolled individual. Frequently, we are interested in understanding if there are relationships between the data, i.e. in testing the existence of associations between the variables.
