The goal of our statistical models is to obtain the best possible understanding of the download and revenue volume associated with any app store top chart across the different categories and countries in our database.
To that end, we:
- Plot store ranks against actual download / revenue data on a daily basis
- Use statistical analysis to create estimate models
- Estimate models then predict downloads / revenues for every rank
For apps that spend a lot of time outside of the ranks, our models are less effective, and the resulting estimates, while still providing a good indication, are less accurate.
Our models are highly dynamic and improve over time as we continue to obtain grow our data partner base and monitor the app stores. For every update to our statistical models, we also perform a full re-run of the historical data base to ensure that the consistency and quality throughout the platform.
