Cohort is ideal for analyzing user retention analysis, or it’s opposite – churn. For retention you would measure the recency of visits to the site, or purchases and for churn the same, just looking at when visits, plays or purchases stopped recurring for a specific cohort of users. It's essentially a visit log of sorts, as it holds all the necessary data for creating a cohort analysis. Each registration week is a cohort. To know how many people are part of the cohort I can use: visit_log.groupby('RegistrationWeek').AccountID.nunique() What I want to do is create a pivot table with the registration weeks as keys. python statsmodels numpy seaborn Time-Series Forecasting Models Given a historical dataset, I've worked to decompose components of the time-series, engineer significant features and build models to predict future performance.
