Basic Linear Regressions for Finance

May 21, 2020 | R Tutorials

Linear Regression In statistics, linear regression is a linear approach to modeling the relationship between a scalar response (or dependent variable) and one or more explanatory variables (or independent variables). The relationships are modeled using linear basis functions, essentially replacing each input with a function of the input. This is ...
