We mentioned that the correlation between species scores and sample scores is maximized. Note that it is difficult to see a unified trend or structure in the data set. Now let us arrange our columns in order of ascending sample score, and our rows in order of ascending species score. The first row consists of the sample scores. Now the data matrix has a definite data structure.
Numbers tend to be clustered around the diagonal.
Thus there is a correspondence between species and samples in the above data. Note that there is a correlation between species scores and sample scores. The weighted correlation coefficient of the above scatter diagram will be equal to the eigenvalue of the first axis, which is 0.7791. This page was created and is maintained by Michael Palmer.
