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. WebAug 25, 2024 · It’s the right time to uncover the Logistic Regression in R. Summary. We have seen how OLS regression in R using ordinary least squares exist. Also, we have learned its usage as well as its command. Moreover, we have studied diagnostic in R which helps in showing graph.
