my research area is water quality assessment. in this regard i wish to learn about various statistical methods such as PCA , CA etc.. can anyone help me in finding out various institutes or training centers available in the field..
Clustering models dividing data into groups that were not previously defined. This ensures that the data points in a particular group are similar unlike the other groups. Because of unknown groups to where cases are to be assigned, they sometimes referred to unsupervised machine learning. Testing the quality of clusters depend on the algorithms used. Hierarchical clustering quality using Tangle gram () function that is implement in R programming. This is compared one Hierarchical clustering and other in terms of its fit
To start with, you may read "An Introduction to Clustering and different methods of clustering" via analytics vidhya
Mbukwa, you do not really have to find an institution that teaches only PCA or Cluster Analysis. Any institution that is involved in social studies research especially postgraduate courses in sociology, geography, psychology and urban studies will have experts in PCA (principal components analysis) which is a particular type of Factor Analysis in which the factors have been rotated maximally to be at right angles with each other. In effect, factors (now referred as components) are said to be orthogonal. In the mean time, you can consult an SPSS manual and and then go on from there.
In the same manner you can consult any of the texts on Cluster Analysis. These texts will be very useful to you whether or not you are able to find an institution that just specializes in teaching them.
FOLLOW-UP.
Dr Mbukwa , please pardon my reference to you. My reference is actually for
Harold, I think his phrase was misunderstood to me clearly. Well, what i can say is PCA and Cluster analysis are the sub-topics in Applied Multivariate Statistics course taught though at postgraduate level for MSc. Statistics.
Find the attached book related Multivariate and analysis using R. Hope will be useful too
Easiest way would be to use minitab statistical software or JMP software and look into multivariate statistic tool in them .You can get good idea for your data to be used for cluster and PCA analysis.You can get free downloads of minitab versions on the net.
Dear Kumar. apart from miniab software, you can really obtain practical applications of PCA from SPSS package.
For Cluster Analysis you may wish to refer to Anderberg, M.R.( 1973) " Cluster Analysis for Applications"
