Practical Guide to Cluster Analysis in R Quick start Data preparation: # Load datadata("USArrests") my_data <- USArrests# Remove any missing value (i.e, NA values for not available)my_data <- na.omit(my_data)# Scale variablesmy_data <- scale(my_data)# View the firt 3 rowshead(my...
Cluster Analysis In the context ofcustomer segmentation, customer clustering analysis is the use of a mathematical model to discover groups of similar customers based on finding the smallest variations among customers within each group. These homogeneous groups are known as “customer archetypes” or “...
In general bio- informatics aims to solve complicated problems. Examples: - categorized gene with their functionality, analysis of gene expression data obtained from micro-array experiments etc. However, the large number of genes and the complexity of biological networks greatly increase the challenges...

Our analysis indicates that the strong clustering aligns with the halo assembly bias seen in simulations3 with the standard ΛCDM cosmology only if more diffuse dwarfs formed in low-mass halos of older ages. This pattern is not reproduced by existing models of galaxy evolution in a ΛCDM ...
5p and 3p miRNA strands have different mRNA-targeting sequences and may both functionally impact gene expression in cancer. Here, the authors undertake a pan-cancer analysis that indicates 5p/3p miRNA strands function together to regulate tumorigenic processes. Ramkrishna Mitra , Clare M. Adams &...
In an example, Principal Component Analysis (PCA) [19] is a method that transforms sample attributes into a form that would have the highest variance, thus more suitable for discrimination tasks with an additional benefit of reduced dimensions. In general, this concept can directly be generalized...
