OUR METHODOLOGY
18
The distribution of app store downloads and revenue across top chart ranks follows a predictive curve. With the help of data from our data partners, we can determine what this curve looks like. As a result, we're able to get estimates at every rank position.

HOW WE KNOW IF IT IS ACCURATE (AND WHAT IS THE MAPE)
Best Rank Observed - 'Overall'*

32
The only way for us to measure the accuracy of our data is to use the MAPE (Median Absolute Percentage Error). We calculate the percentage of error between the actual downloads we get from our partners with the estimations we get after data modelization and look at the median for a given country. In short, the lower the MAPE, the better the accuracy.MAPE - Downloads10.6%26.1%

WHY WE DO MODEL UPDATES
40
We’re always looking to improve the accuracy of our data. The more data we pull in from data partners, the better our estimates get. That’s why, when we get significant quantities of data from new partners, we refit our models.
