Example #

Returns count, min, max, avg, sum, sum_of_squares, variance, variance_population, variance_sampling, std_deviation, std_deviation_population, std_deviation_sampling plus std_deviation_bounds (upper/lower at ±2σ).

Parameters for extended_stats #

• field
  (Required, string) Numeric field you wish to aggregate.
• sigma
  (Optional, float, default: 2) Multiplier for the standard deviation bounds.
