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
dataRobotModel. A DataRobot model object like that returned by
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.
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.
