cluster analysis; by giving a general background for cluster analysis; and explaining the concept of cluster analysis and how the clustering algorithms work. A basic idea and the use of each clustering method will be described with its graphical features. Different clustering techniques are also explained with examples to get a better idea. The two main clustering techniques (Hierarchical and K-means Partitioning) are illustrated using a sample data set ‘IRIS FLOWER DATA SET’ (1936)‚ where a

They provide an opportunity for researchers to discover unanticipated information regarding the domain of study. However‚ they are problematic for processing since they are unstructured questions to which

Research Objective: Analyze the decision that Dr Kuah‚ CEO of Royal Bank of Scotland need to consider on relocating the headquarters from Glasgow to Leeds‚ Yorkshire. For example‚ what are the causes‚ costs and benefits of clustering in Leeds. Research Questions: To be able to make decision on financial service clustering in Leeds‚ Dr Kuah should consider:

thus it is expected that future studies will develop statistical models which consider both time and clustering effects to calculate the power of trials. Considering other factors - such as the number of randomization steps – which can influence the trial’s outcomes‚ is beneficial to increase the accuracy of the presented inferences. Due to the dependency of the intervention effect on time and clustering‚ proposing a method to extract the intervention effects are highly dependent on the trial’s characteristics
