This powerful function from scipy.optimize module can fit any user-defined function to a data set by doing least-square minimization. For simple linear regression, one can just write a linear mx+c function and call this … In statistics, linear regression is a linear approach for modelling the relationship between a scalar response and one or more explanatory variables (also known as dependent and independent variables). The case of one explanatory variable is called simple linear regression; for more than one, the process is called multiple linear regression. This term is distinct from multivariate linear regression, where multiple correlated dependent variables are predicted, rather than a single sca…
