5 Data Analysis

the first principal component, along the axis of the data. U nlike the coefficient

of determination for 2-D scatters, this measure does distinguish predictor

and response variables.

Scatter Plot Arrays

Use the MATLAB plotmatrix function to make comparisons of the

relationships between multiple pairs of intersections:

figure

plotmatrix(count)

The plot in the (i, j)th position of the array is a scatter with the i th variable

on the vertical axis and the j th variable on the horizontal axis. The plot in

the i th diagonal position is a histogram of the i th variable.

See “Plotting Data” in the MATLAB Data Analysis documentation for more

information on statistical visualization.
