Sigma Computing Documentation

These functions work best with aggregated data in a grouped table. For a video explanation of working with functions of this type, see Getting started with functions and groupings in Sigma.

Aggregate functions evaluate multiple rows of data to return a single value. For example, you can use aggregate functions to perform group calculations (like Sum and Avg), retrieve specific values (like Min and Max), assess the data to provide insights (like Count and CountDistinct), or join multiple values (like ArrayAgg and ListAgg).

Function	Description
ArrayAgg	Identifies non-null row values in a column or group and aggregates them into a single array.
ArrayAggDistinct	Identifies distinct non-null row values in a column or group and aggregates them into a single array.
Avg	Calculates the average value of a column or group.
AvgIf	Calculates the average value of a column or group when the specified condition is `True`.
Corr	Calculates the Pearson correlation coefficient (bivariate correlation) of two columns.
Count	Counts the number of non-null and non-empty values in a column or group.
CountDistinct	Counts the number of unique non-null and non-empty values in a column or group. Does not count duplicate values. (Same as Ndv.)
CountDistinctIf	Counts the number of unique non-null and non-empty values in a column or group when the specified condition is `True`. Does not count duplicate values.
CountIf	Counts the number of non-null and non-empty values in a column or group when the specified condition is `True`.
GrandTotal	Calculates the grand total for column or group.
ListAgg	Joins the values of a group or column into a single text string.
ListAggDistinct	Joins the unique values of a group or column into a single text string. Does not include duplicate values.
Max	Retrieves the maximum (largest or latest) value in a column or group.
MaxIf	Retrieves the maximum (largest or latest) value in a column or group when the specified condition is `True`.
Median	Determines the median (midpoint) value of a column or group.
Min	Retrieves the minimum (smallest or earliest) value in a column or group.
MinIf	Retrieves the minimum (smallest or earliest) value in a column or group when the specified condition is `True`.
PercentileCont	Calculates the continuous k^th percentile of a column or group.
PercentileDisc	Calculates the discrete k^th percentile of a column or group.
PercentOfTotal	Calculates the percentage a value contributes to the specified aggregate total.
RegressionIntercept	Calculates the y-intercept of the linear regression line.
RegressionR2	Calculates the coefficient of determination of the linear regression line.
RegressionSlope	Calculates the slope of the linear regression line.
StdDev	Calculates the standard deviation of a column or group.
Subtotal	Calculates the subtotal of a column or group.
Sum	Calculates the sum of a column or group.
SumIf	Calculates the sum of a column or group when the specified condition is `True`.
SumProduct	Calculates the product of row values across specified columns, then calculates the sum of the resulting products for a column or group.
Variance	Estimates the sample variance (spread of distribution) of a column or group.
VariancePop	Calculates the population variance (spread of distribution) of a column or group.
