What did the update do?

For this release we re-fit our models on historical data provided from
additional publisher partners. Additionally we have changed our methodology to include a longer time window. This enables us to better capture historical trends in our model.

Together, these factors generally caused our estimates for the total market
size of each country to change. In most countries, the estimated market
size increased; certain Asian markets were typically the exception. The table
below summarizes these changes for the top 10 markets on iOS (iPhone only).

As a result of the enriched data set, accuracy in terms of MAPE between Q1
and Q3 2017 improved on average by 2 percentage points for each
market. MAPE in the top 10 markets all saw significant improvements. The
table below summarizes the MAPE for the top ten markets oniOS (iPhone only).

Overall, better models means better accuracy. It's important to note that the changes in our estimates might affect some apps, publishers, and categories more dramatically than others.
