Factor Analysis is the attempt to find new components in a model that attempt to model the same data. Assignment help of this kind involves finding new variables to represent the ones given such that there are less of them. An example of a popular method for homework help is principal component analysis (PCA), where one finds components based of the eigenvalues in the covariance and correlation matrices.
Note: The following is an example of factor analysis created by me. It is not a representation of an assignment submission due to confidentiality concerns. Nevertheless, the assignment is a genuine product of mine representing the types of work that I can do.
