This function is only available when connected to a Teradata database.
An enhanced version of the standard kurtosis function is supported, generating KURTOSIS (expression) and returning a type of float. When dragging a Kurtosis into a variable, the following tree element is created.
Columns and/or other non-aggregate expressions can be moved over the (empty) branch of the tree.
The enhancement consists of the ability to compute the kurtosis of a date expression, generating KURTOSIS (date expression - DATE '1900-01-01').
The standard option to compute the kurtosis over distinct values only is also provided, resulting in the generation of KURTOSIS(DISTINCT expression). This option is enabled through the Properties panel. Double-click on Kurtosis, or highlight it and click Properties.
