10.6 rain demo variable importance

Variable Importance

One aspect of understanding the data and models that we build is what variables play the most significant role in predicting the outcome.

The variables that are actually end up in the model are: humidity_3pm, rainfall, wind_gust_speed.

All variables are considered in the modelling and the relative importance of each variable in predicting the outcome is determined. Note that in the table below the actual numbers represent the relative importance of that variable.

Relative Importance of Variables:

   humidity_3pm wind_gust_speed        rainfall    humidity_9am       cloud_3pm
