Here, the norm of residuals (the usual metric) is least when eliminating ‘row=2’, and greatest when eliminating ‘row=6’. Experiment to get the result you want. In that simulation, you are defining a particular slope and intercept and adding a normally-distributed random vector to it.

WebResiduals are one way to check the regression coefficients or other values in linear regression. Then the residual equation is, ε = y − y ^. The predicted value of y will be y ^ = a + b x for linear regression y = a + b x + ε. A residual plot can at times be good to identify potential problems in the regression model.
