Package dk.alexandra.fresco.stat.regression.logistic

Class LogisticRegression

java.lang.Object
dk.alexandra.fresco.stat.regression.logistic.LogisticRegression
All Implemented Interfaces:
dk.alexandra.fresco.framework.builder.Computation<ArrayList<dk.alexandra.fresco.framework.DRes<dk.alexandra.fresco.lib.fixed.SFixed>>,​dk.alexandra.fresco.framework.builder.numeric.ProtocolBuilderNumeric>
public class LogisticRegression
extends Object
implements dk.alexandra.fresco.framework.builder.Computation<ArrayList<dk.alexandra.fresco.framework.DRes<dk.alexandra.fresco.lib.fixed.SFixed>>,​dk.alexandra.fresco.framework.builder.numeric.ProtocolBuilderNumeric>
A naive implementation of logistic regression, not optimized for secure computation. Given a data set consisting of column vectors and a list of expected classifications (0 or 1), this computation performs a linear regression on the data and the expected outcome as log-odds.
