We will first learn about the fundamentals of R clustering, then proceed to explore its applications, various methodologies such as similarity aggregation and also implement the Rmap package and our own K-Means clustering algorithm in R. 1. The Cluster Analysis in SPSS The objective of cluster analysis is to partition a set of objects into two or more clusters such that objects within a cluster are similar and objects in different clusters are dissimilar. Objective of Cluster Analysis. Ondanks de ruime keuze in softwarepakketten om data te verwerken is Microsoft Excel is nog steeds een van de meest gebruikte tools om analyses en rapportages te maken. Other techniques you might want to try in order to identify similar groups of observations are Q-analysis, multi-dimensional scaling (MDS), and latent class analysis.
