| SimpleLinearRegression | | public class SimpleLinearRegression extends Classifier implements WeightedInstancesHandler(Code) | |
Learns a simple linear regression model. Picks the attribute that results in the lowest squared error. Missing values are not allowed. Can only deal with numeric attributes.
Valid options are:
-D
If set, classifier is run in debug mode and
may output additional info to the console
