Earth Engine is introducingnoncommercial quota tiersto safeguard shared compute resources and ensure reliable performance for everyone. All noncommercial projects will need to select a quota tier byApril 27, 2026or will use the Community Tier by default. Tier quotas will take effect for all projects (regardless of tier selection date) onApril 27, 2026.Learn more.
ee.Reducer.robustLinearRegressionStay organized with collectionsSave and categorize content based on your preferences.
Creates a reducer that computes a robust least squares regression with numX independent variables and numY dependent variables, using iteratively reweighted least squares with the Talwar cost function. A point is considered an outlier if the RMS of residuals is greater than beta.
Each input tuple will have values for the independent variables followed by the dependent variables.
The first output is a coefficients array with dimensions (numX, numY); each column contains the coefficients for the corresponding dependent variable. The second is a vector of the root mean square of the residuals of each dependent variable. Both outputs are null if the system is underdetermined, e.g., the number of inputs is less than numX.
