- population file: a list of unique `ID`s you want processed
- arguments:
- T: the prediction time. Time-dependent features will be generated using data in $`t\in[0,T]`$.
- T: The time of prediction; time-dependent features will be generated using data in $`t\in[0,T]`$.
- dt: the temporal granularity at which to "window" time-dependent data.

- theta_2
- theta_freq
- theta_1: The threshold for Pre-filter.
- theta_2: The threshold for Post-filter.
- theta_freq: The threshold at which we deem a variable “frequent” (for which summary statistics will be calculated).
- stats_functions: A set of 𝐾 statistics functions (e.g., min, max, mean). Each function is used to calculate a summary value using all recordings within a single time bin. These functions are only applicable to “frequent” variables as determined by theta_freq.
Output: The generated features and associated metadata are located in `{data_path}/`:
