Hello everyone I am currently trying to perform a simple logistic regression on a hotel dataset trying to predict whether customers are more likely to book a classic_roomtype or not, based on variables like amount, frequency of visits, number of nights spent e.t.c.  The problem is after running the model everything works fine except that in viewing my results there is no data pane to actually view in text the accuracy of the model. and yes the accuracy box have been checked. I don't know if it's a problem of the version of rapid miner am using or there's a setting I haven't quite checked yet. Would really appreciate your help.

In my results overview pane, the only thing that shows is the Description, Weight Table, Support Vector table, Charts, and Annotation
