PPT-Canonical Correlation/Regression

Canonical CorrelationRegression AKA multiple multiple regression AKA multivariate multiple regression Have two sets of variables Xs and Ys Create a pair of canonical variates a 1 X. and regression. Scatter plots. A scatter plot is a graph that shows the relationship between the observations for two data series in two dimensions.. Scatter plots are formed by using the data from two different series to plot coordinates along the . The Data. http://. core.ecu.edu/psyc/wuenschk/SPSS/SPSS-Data.htm. Corr_Regr. See .
