Psych 285: Computational Statistics
and Statistical Visualization

Professor Forrest Young


Assignment 2
Functional Programming - 2
Due Friday, Feb 2


Write NORMALIZE, a function that normalizes a matrix X (i.e., makes the mean of each column Mean and the standard deviation StDev).

The function should take a matrix X as its only required argument, with keyword arguments Mean (default 0.0) and StDev (default 1.0).

The function should return a list whose first element is the normalized matrix, second element is a list or vector of column means of X, and third elements is a list or vector of column standard deviations of X.

You should base this function on one of the two CENTER functions.

Please send your code to me by e-mail before class on the due date.
