Package sampler produces strats and stratified samples. The package works with ClickHouse tables. This package does two things: The goal is to generate a sample with an equal number of rows for each stratum. A sample rate for each stratum is determined to achieve this. If each stratum has sufficient rows, then we're done. To the extent some strata have insufficient rows, then the total sample will be short. Also, the sample won't be exactly balanced. To achieve balance one would have to do one of these: Practically, the first is not an option as often there will be a stratum with very few rows. The second is tantamount to up-weighting the small strata. In that case, these observations may become influential observations. Instead of these, this package adopts the philosophy that an approximate balance goes a long way to reducing the leverage of huge strata which is typical in data. The sampling algorithm used by sampler is: 1. At the start 2. Update Step 2 is repeated (iterations capped at 5) until the target sample size is achieved (within tolerance) or no strata have free observations.
