Overview

Transformations allowed on the dataset. Supported transformations are Filling and Aggregation. Filling specifies how to add values to missing values in the dataset. Aggregation defines how to aggregate data that does not align with forecast frequency.

#aggregation ⇒ Hash<String,String>
A key value pair defining the aggregation method for a column, where the key is the column name and the value is the aggregation method.
#filling ⇒ Hash<String,Hash<String,String>>
A key value pair defining the filling method for a column, where the key is the column name and the value is an object which defines the filling logic.

Instance Attribute Details

#aggregation ⇒ `Hash<String,String>`

A key value pair defining the aggregation method for a column, where the key is the column name and the value is the aggregation method.

The supported aggregation methods are sum (default), avg, first, min, max.

Aggregation is only supported for the target column.

Returns:

(Hash<String,String>)

#filling ⇒ `Hash<String,Hash<String,String>>`

A key value pair defining the filling method for a column, where the key is the column name and the value is an object which defines the filling logic. You can specify multiple filling methods for a single column.

The supported filling methods and their corresponding options are:

frontfill: none (Supported only for target column)
middlefill: zero, value, median, mean, min, max
backfill: zero, value, median, mean, min, max
futurefill: zero, value, median, mean, min, max

To set a filling method to a specific value, set the fill parameter to the chosen filling method value (for example "backfill" : "value"), and define the filling value in an additional parameter prefixed with "_value". For example, to set backfill to a value of 2, you must include two parameters: "backfill": "value" and "backfill_value":"2".
