There are two types of panel data:. Exactly how large a VIF has to be before it causes issues is a subject of debate. Multiple regression (an extension of simple linear regression) is used to predict the value of a dependent variable (also known as an outcome variable) based on the value of two or more independent variables (also known as predictor variables). Panel data or longitudinal data (the older terminology) refers to a data set containing observations on multiple phenomena over multiple time periods. Factor analysis assumes the existence of a few common factors driving the variation in the data, while principal component analysis does not.
