WebIn 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 … Webplot (mpg ~ wt, data = mtcars, col=2) The plots shows a (linear) relationship!. Then if we want to perform linear regression to determine the coefficients of a linear model, we would use the lm function: fit <- lm (mpg ~ wt, data = mtcars) The ~ here means "explained by", so the formula mpg ~ wt means we are predicting mpg as explained by wt. green gables golf course map
