I am not familiar with Linear Regression models...I have built Logistic Regression so fat...So I just wanted to know how do you know if a Linear model is good in Enterpriise Miner..What are the metrics or graphs to measure the performance? In Logistic Regression, you have AUC, Roc Chart, Gain Chart etc...what do I look at to tell if the prediction is good in Linear Regression...Can we get a good linear regression model with a Low R-square like below for eaxmple? On my grah (results from EM) My mean predicted and mean target are quite close..Is it enought to conclude? Thank you...
