UnivariateLinearRegressionSubstitution

class UnivariateLinearRegressionSubstitution extends ImputationStrategy

An imputation strategy that is based on Linear Regression which is an approach for modeling the relationship between a scalar dependent variable y and an explanatory variable x. This strategy imputes the value of y by : slope * x + intercept This implementation is only for imputing numeric columns.
