ListResidualsCharts: Retrieve residuals chart data for a model for all available data partitions (see
DataPartition). This chart is only available for regression models that are not
time-aware.
Description
Retrieve residuals chart data for a model for all available data partitions (see
DataPartition). This chart is only available for regression models that are not
time-aware.
list of objects containing residuals chart data for all available data partitions. See
DataPartition for details. Each object has the following components:
residualMean. Numeric: the arithmetic mean of the predicted value minus the actual value
over the downsampled dataset.
coefficientOfDetermination. Numeric: aka the r-squared value. This value is calculated
over the downsampled output, not the full input.
data. data.frame: The rows of chart data in [actual, predicted, residual, row number]
form. If the row number was not available at the time of model creation, the row number will
be null.
histogram. list: Data to plot a histogram of residual values. Each object contains:
intervalStart. Numeric: Start value for an interval, inclusive.
intervalEnd. Numeric: End value for an interval, exclusive for all but the last
interval.
occurrences. Integer: the number of times the predicted value fits within the
interval.
Arguments
model
dataRobotModel. A DataRobot model object like that returned by GetModel. The model
must be a regression model that is not time-aware.
fallbackToParentInsights
logical. If TRUE, this will return the residuals chart data for
the model's parent if the residuals chart is not available for the model and the model has a
parent model.
