AVG([DISTINCT] expression)
Returns the average of the values of field expression.
- expression: The expression to use to compute the average.
COUNT([DISTINCT] expression)
Returns the number of occurrences of the field expression. To indicate a specific field value to match, format expression as eval(field="value").
- expression: The expression to use to compute the count.
EARLIEST(expression)
Returns the chronologically earliest seen value of expression.
- expression: The expression to use to compute the earliest.
LATEST(expression)
Returns the chronologically latest seen value of expression.
- expression: The expression to use to compute the latest.
MAX([DISTINCT] expression)
Returns the maximum value of the field expression. If the values of expression are non-numeric, the max is found from alphabetical ordering.
- expression: The expression to use to compute the max.
MEDIAN(expression)
Returns the middle-most value of the field.
- expression: The expression to use to compute the median.
MIN([DISTINCT] expression)
Returns the minimum value of the field expression. If the values of expression are non-numeric, the min is found from alphabetical ordering.
- expression: The expression to use to compute the min.
MODE(expression)
Returns the most frequent value of the field expression.
- expression: The expression to use to compute the mode.
RANGE(expression)
Returns the difference between the max and min values of the field expression.
- expression: The expression to use to compute the range.
SUM([DISTINCT] expression)
Returns the sum of the values of the field expression.
- expression: The expression to use to compute the sum.
SUMSQ(expression)
Returns the sum of the squares of the values of the field expression.
- expression: The expression to use to compute the sum of the squares.
STDEV(expression)
Returns the sample standard deviation of the field expression.
- expression: The expression to use to compute the sum of the STDEV.
STDEVP(expression)
Returns the population standard deviation of the field expression.
- expression: The expression to use to compute the sum of the STDEVP.
VAR(expression)
Returns the sample variance of the field expression.
- expression: The expression to use to compute the sum of the VAR.
VARP(expression)
