LevenbergMarquardtEstimation	Implementation of the nonlinear regression algorithm, known as Levenberg-Marquardt Estimation (or LMA).
LinearBasisRegression<InputType>	Computes the least-squares regression for a LinearCombinationFunction given a dataset.
LinearRegression	Computes the least-squares regression for a LinearCombinationFunction given a dataset.
LinearRegression.Statistic	Computes regression statistics using a chi-square measure of the statistical significance of the learned approximator

LocallyWeightedFunction.Learner<InputType,OutputType>	Learning algorithm for creating LocallyWeightedFunctions.
LogisticRegression	Performs Logistic Regression by means of the iterative reweighted least squares (IRLS) algorithm, where the logistic function has an explicit bias term, and a diagonal L2 regularization term.
LogisticRegression.Function	Class that is a linear discriminant, followed by a sigmoid function.
MultivariateLinearRegression	Performs multivariate regression with an explicit bias term, with optional L2 regularization.
ParameterDerivativeFreeCostMinimizer	Implementation of a class of objects that uses a derivative-free minimization algorithm.
ParameterDerivativeFreeCostMinimizer.ParameterCostEvaluatorDerivativeFree	Function that maps the parameters of an object to its inputs, so that minimization algorithms can tune the parameters of an object against a cost function.
ParameterDifferentiableCostMinimizer	This class adapts the unconstrained nonlinear minimization algorithms in the "minimization" package to the task of estimating locally optimal (minimum-cost) parameter sets.
ParameterDifferentiableCostMinimizer.ParameterCostEvaluatorDerivativeBased	Function that maps the parameters of an object to its inputs, so that minimization algorithms can tune the parameters of an object against a cost function.
UnivariateLinearRegression	An implementation of simple univariate linear regression.
