We learned that the modified Gompertz model via nonlinear regression usingthe least square method was the most effective model to describe the growth curve. Nevertheless,the use of statistical tests to choose the best model relies heavily on the residuals of the curve tobe statistically robust. ...
or p-values (CI's and p's are just flip sides of the same coin), now we do need to make distributional assumptions (sort of...). In this case, it is the residuals (y

By now any semblance of normality had disappeared. 到了现在,任何常态的假象都消失了。 They are hoping for a return to normality now that the war is over. 既然战争结束了,他们希望一切都恢复常态。 权威例句 A test for normality of observations and regression residuals ...
We attempt to investigate the effects of using residuals from robust regression replacing OLS residuals in test statistics for the normality of the errors. We have found that this can lead to substantially improved ability to detect lack of normality in suitable situations. We derive the asymptotic...
