Detailed Description

Comma separated list of the statistics to calculate, e.g.

"sum,mean". Supported values:

COUNT: Number of objects (independent of the given column(s)).
MEAN: Arithmetic mean (average), equivalent to sum/count.
STDV: Sample standard deviation (denominator is count-1).
VARIANCE: Unbiased sample variance (denominator is count-1).
SKEW: Skewness (third standardized moment).
KURTOSIS: Kurtosis (fourth standardized moment).
SUM: Sum of all values in the column(s).
MIN: Minimum value of the column(s).
MAX: Maximum value of the column(s).
WEIGHTED_AVERAGE: Weighted arithmetic mean (using the option weight_column_name as the weighting column).
CARDINALITY: Number of unique values in the column(s).
ESTIMATED_CARDINALITY: Estimate (via hyperloglog technique) of the number of unique values in the column(s).
PERCENTILE: Estimate (via t-digest) of the given percentile of the column(s) (percentile(50.0) will be an approximation of the median). Add a second, comma-separated value to calculate percentile resolution, e.g., 'percentile(75,150)'
PERCENTILE_RANK: Estimate (via t-digest) of the percentile rank of the given value in the column(s) (if the given value is the median of the column(s), percentile_rank(<median>) will return approximately 50.0).

A set of string constants for the parameter stats.
