system.math.kurtosis
This function is used in Python Scripting.
Description​
Calculates the kurtosis of a sequence of values. Kurtosis measures if data is peaked or flat relative to normal distribution. A set of data with high kurtosis will have distinct peaks near the mean, while a set of data with low kurtosis will have a flat top near the mean. Uniform distribution is typically a flat line.
Returns NaN (Not a Number) if passed an empty sequence measure of whether the data are heavy-tailed or light-tailed of a given distribution.

Syntax​
system.math.kurtosis(values)
Parameters​
| Type | Parameter | Description |
|---|---|---|
| List[Float] | values | A sequence of numerical values. Accepts both integers and floats. The sequence may not contain None type values. However, passing a None type object instead of a sequence of numerical values will return NaN. Requires at least four items in the list. |
Returns​
Float - The kurtosis, or NaN if the input was empty or null. Additionally, returns NaN if the values returned fewer than four values.
Scope​
Gateway, Vision Client, Perspective Session
Code Examples​
# Create a List of values.
values = [3.5, 5.6, 7.8, 7.4, 3.8]
# Prints the resulting value.
print system.math.kurtosis(values)
