FlexAlpha


Unit:SDL_dendrogram
Class:TDendrogram
Declaration:property FlexAlpha: double;

The property FlexAlpha controls the kind of clustering if the property ClusterMethod is set to cmFlexLink. FlexAlpha may take values between 0.5 and 1.0; by default, FlexAlpha is set to 0.5 (which creates the same dendrogram as average linkage (cmAvgLink) does).

Hint: Changing the property FlexAlpha triggers the recalculation of the dendrogram. In order to prevent multiple recalculations if several clustering parameters are to be changed, the property SuppressClustAnal should be set to TRUE prior to changing any parameters of the clustering algorithm.

Example: This property is used in the following example program (see http://www.lohninger.com/examples.html for downloading the code): dendro
