The expression can use inline functions. For example, to calculate the maximum over an average of a multivalued column, use MV_AVG to first average the multiple values per row, and use the result with the MAX function

FROM employees
| STATS max_avg_salary_change = MAX(MV_AVG(salary_change))
max_avg_salary_change:double
13.75
