`dataFrame.column.stat — smooth()`

Description

The smooth() method of the stat object returns a smoothed version of the values in the selected column using a moving average.

Signature

dataFrame.column(columnName).stat.smooth({ windowSize: 3 })

Scope: column
Family: stat
Returns: mask

Argument

columnName (string): The name of the column from which to compute skewness.
options (object): Smoothing options.

Option

windowSize (number): The number of values included in each smoothing window. (Default: 3.)

Returns

mask ( number[] ): An array containing the smoothed values.

Notes

Larger window sizes produce smoother results.
Smaller window sizes preserve more local variation.
A value close to zero indicates a roughly symmetric distribution.

Example

// get the smooth values of a column of the dataFrame
var mask = dataFrame.column('revenue').stat.smooth();

// add smooth values to the dataFrame
dataFrame.column('smooth').set(mask);
