SSH into the box and run the setup script: $ ssh @ $ sh setup.sh 20240119 . This will take a few minutes. ppt on e learningMallows's Cp addresses the issue of overfitting, in which model selection statistics such as the residual sum of squares always get smaller as more variables are added to a model. Thus, if we aim to select the model giving the smallest residual sum of squares, the model including all variables would always be selected. Instead, the Cp statistic calculated on a sample of data estimates the sum squared prediction error (SSPE) as its population target ppt on effective listening

WebAIC [Akaike (1973)], Mallows' Cp [Mallows (1973)] and the Bayesian informa-tion criterion BIC [Schwarz (1978)], use a fixed penalty on the size of a model. Some new variable selection procedures suggest the use of a data adaptive penalty to replace fixed penalties [i.e., Bai, Rao and Wu (1999) and Shen and Ye (2002)].
