Root mean square method
WebRemember that lw_mse returns the mean squared error, so we have to take the square root to get the rmse. lw_mse ( lw_reg_slope , lw_reg_intercept ) ** 0.5 2701.690785311856 WebThe root mean square of a data set is exactly what it sounds like: it is the result of the square root of the mean of each item in a data set squared. There are specific applications for this, such as when trying to find the mean of an alternating data set, where the raw mean would always be 0.
