NGroups​

Property NGroups As %Integer;

Dim​

Property Dim As %Integer;

UseMahalanobisDistance​

Methods​

%OnOpen​

Method %OnOpen() As %Status [ Private, ServerOnly = 1 ]

This callback method is invoked by the %Open method to provide notification that the object specified by oid is being opened.

If this method returns an error then the object will not be opened.

Create​

Method Create(N As %Integer, M As %Integer, ByRef data As %Double, ByRef groups As %Integer, p As %Boolean) As %Status

getConfusionMatrixForTestSet​

Method getConfusionMatrixForTestSet(rs As %ResultSet, i1 As %Integer, dim As %Integer, Output C, Output r As %Double) As %Status

printConfusionMatrix​

Method printConfusionMatrix(ByRef confusion = "") As %Status

getSensitivity​

Method getSensitivity(g, Output sc As %Status, ByRef confusion = "") As %Double

getSpecificity​

Method getSpecificity(g, Output sc As %Status, ByRef confusion = "") As %Double

GetDF​

Method GetDF(ByRef x, Output fv, verobse As %Boolean = 1) As %Status

getCovector​

Method getCovector(target As %String, Output V) As %Status

GetMajorContributors​

Method GetMajorContributors(targetPos As %String, targetNeg As %String, margin As %Double, Output listPos As %List, Output listNeg As %List) As %Status

predict​

Method predict(ByRef x, Output sc As %Status, Output maxf As %Double, Output f) As %String

GetMahalanobisDistance​

Method GetMahalanobisDistance(ByRef x, Output fv, verobse As %Boolean = 0) As %Status

%OnNew​

Method %OnNew(name As %String) As %Status [ Private, ServerOnly = 1 ]

This callback method is invoked by the %New method to provide notification that a new instance of an object is being created.

If this method returns an error then the object will not be created.

It is passed the arguments provided in the %New call. When customizing this method, override the arguments with whatever variables and types you expect to receive from %New(). For example, if you're going to call %New, passing 2 arguments, %OnNew's signature could be:

Method %OnNew(dob as %Date = "", name as %Name = "") as %Status If instead of returning a %Status code this returns an oref and this oref is a subclass of the current class then this oref will be the one returned to the caller of %New method.
