Ordinary Least Squares (OLS) using statsmodels

Web02. dec 2014. · Discussions (2) [x, ind] = OLS (A,b,r) gives the solution to the least squares problem. using only the best r regressors chosen from the ones present in matrix A. This function also returns in the vector ind the indexes of the. best r regressors (i.e., the best columns of A to use). In statistics, ordinary least squares (OLS) is a type of linear least squares method for choosing the unknown parameters in a linear regression model (with fixed level-one effects of a linear function of a set of explanatory variables) by the principle of least squares: minimizing the sum of the squares of the differences between the observed dependent variable (values of the variable being observed) in the input dataset and the output of the (linear) function of the independent variable. Webolsrr is built with the aim of helping those users who are new to the R language. If you know how to write a formula or build models using lm, you will find olsrr very useful. Most of the functions use an object of class lm as input. So you just need to build a model using lm and then pass it onto the functions in olsrr.
