GetResidualsChart: Retrieve residuals chart data for a model for a data...

In datarobot: 'DataRobot' Predictive Modeling API

Retrieve residuals chart data for a model for a data partition (see DataPartition).

Description

Retrieve residuals chart data for a model for a data partition (see DataPartition).

Usage

GetResidualsChart(
  model,
  source = DataPartition$VALIDATION,
  fallbackToParentInsights = FALSE
)

Arguments

model	dataRobotModel. A DataRobot model object like that returned by GetModel. The model must be a regression model that is not time-aware.
source	character. The data partition for which data would be returned. Default is DataPartition$VALIDATION. See DataPartition for details.
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.

Value

list with a single object containing residuals chart data whose name matches the source requested. See DataPartition for details. This 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, rowNumber]⁠ form. If the row number was not available at the time of model creation, or if working with DataRobot 5.2, which does not provide rowNumber in the API response, the rowNumber will be NA.

• 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.

Examples

## Not run: 
  projectId <- "59a5af20c80891534e3c2bde"
  modelId <- "5996f820af07fc605e81ead4"
  model <- GetModel(projectId, modelId)
  GetResidualsChart(model, source = DataPartition$VALIDATION)

## End(Not run)
