Moving Windows

Method Definition
vDataFrame.cummax Adds a new vcolumn to the vDataFrame by computing the cumulative maximum of the input vcolumn.
vDataFrame.cummin Adds a new vcolumn to the vDataFrame by computing the cumulative minimum of the input vcolumn.
vDataFrame.cumprod Adds a new vcolumn to the vDataFrame by computing the cumulative product of the input vcolumn.
vDataFrame.cumsum Adds a new vcolumn to the vDataFrame by computing the cumulative sum of the input vcolumn.
vDataFrame.rolling Adds a new vcolumn to the vDataFrame by using an advanced analytical window function on one or two specific vcolumns.

Analytic Functions

Method Definition
vDataFrame.analytic Adds a new vcolumn to the vDataFrame by using an advanced analytical function on one or two specific vcolumns.
vDataFrame.asfreq Computes a regular time interval vDataFrame by interpolating the missing values using different techniques.
vDataFrame.sessionize Adds a new vcolumn to the vDataFrame which will correspond to sessions.

Customized Features Creation

vDataFrame.case_when Creates a new feature by evaluating the specified conditions.

Features Transformations

Method Definition
vDataFrame.abs Applies the absolute value function to the input vcolumns.
vDataFrame[].abs Applies the absolute value function to the input vcolumn.
vDataFrame.apply Applies each function of the dictionary to the input vcolumns.
vDataFrame[].apply Applies a function to the vcolumn.
vDataFrame[].apply_fun Applies a default function to the vcolumn.
vDataFrame.applymap Applies a function to all the vcolumns.
vDataFrame[].date_part Extracts a specific TS field from the vcolumn.
