Weather forecast with regression models – part 4

Results so far obtained allow us to predict the RainTomorrow Yes/No variable. As a consequence, we are able so far to predict if tomorrow rainfall shall be above 1mm or not. In case of "at least moderate" rainfall, we would like to be as much reliable as possible in predicting {RainTomorrow "Yes"}. Since RainTomorrow "Yes" is perceived as the prediction of a potential threat of damages due to the rainfall, we have to alert Canberra's citizens properly. That translates in having a very good specificity, as explained in the presecution of the analysis. That is motivated by the fact that weather forecast comprises more than one prediction.
