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. WebIn a linear regression equation Y = a + bX, the fitted or predicted value of Y is the value of Y obtained by substituting specific values of X into the sample regression equation. A parameter estimate is said to be statistically significant if there is sufficient evidence that the true value of the parameter does not equal zero. sharegate chatbot
