Reducing Dimensionality with Principal Component Analysis

CRM data can get very extensive. Each metric you collect could carry some interesting information about your customers. But handling a dataset with too many variables is difficult. Learn how to reduce the number of variables in your data using principal component analysis. Not only does this help to get a better understanding of your data. PCA also enables you to condense information to single indices and to solve multicollinearity problems in a regression analysis with many intercorrelated variables.

PCA for CRM data

Purposes of PCA

Getting to know the data

Exploring the correlation structure

PCA computation

Standardization of data

Compute a PCA

The result object of a PCA
