1. Congratulations!
Congratulations! You made it to the end of the second Foundations of Predictive Analytics course!
2. What you learned...
In this course you learned how to construct a sound basetable that can be used to build predictive models. In general, these are the steps you should follow to construct such a basetable:
First, you need to draw a timeline that corresponds to your problem. When doing so, you need to decide whether a timegap is needed.
Secondly, you reconstruct this timegap in history, taking into account seasonality if necessary, and possibly using several snapshots.
Then, you can determine the population of the basetable and calculate the target values.
Next, you should add predictive variables to the basetable. There can be 10, 100 or even 1000 variables in the basetable, depending on your inspiration and the problem at hand.
After that, you should clean the data by filling out missing values, taking care of outliers or performing transformations.
The result is a ready-to-use basetable that can be used for predictive modeling. The better the basetable, the better the predictive models resulting from it.
3. Congratulations!
Again, you did a great job. You are now ready to start building predictive models and apply them to your business and projects!
