>> Application of Lachenbruch Procedure in Quadratic Case of Discriminant Analysis (by Dewi Rachmatin and Kania Sawitri)

Presented at the National Seminar on Mathematics and Mathematics Education Department of Mathematics Education FPMIPA UPI Year 2009 Abstract The results of research on Linear Discriminant Analysis (LDA) and Quadratic Discriminant Analysis (QDA) mostly use the Apparent Error Rate (APER) method in evaluating grouping rules in Discriminant Analysis. This APER method has the advantage of

>> Data Clustering Using Divisive Analysis Method (Diana) (by: Chandra Gunawan, Dewi Rachmatin, and Maman Suherman)

It was announced at unisba mathematics seminar in 2014 Abstract Cluster Analysis is a data grouping analysis that groups data based on the information specified in the data. The purpose of cluster analysis is for objects in one group to have similarities to each other whereas with different objects the groups have differences. The process

>> Comparison between Agglomerative Method, Divisif Method, and K-Means Method in Cluster Analysis (by Dewi Rachmatin and Kania Sawitri)

It was announced at the UNPAR National Seminar on Mathematics in 2014 Abstract The process of grouping data in cluster analysis can be done with two methods: hierarchy method and non-hierarchy method. Hierarchical methods are clustering methods that form the construction of a hierarchy based on a certain level such as a tree structure. This
