There are some key assumptions that should be met before Pearson’s correlation can be used to give valid results: Figure 1: Scatter plots showing examples of linear and non-linear relationships.

In this task, the canonical correlation analysis is performed, labels are specified to identify each set of canonical variables, and a plot of the canonical variables is requested. You can optionally ...

Your job is to eyeball the plots and estimate a number called R, which measures how correlated the two things are. In the game, R can range from 0 (no correlation at all) to 1 (a perfect positive ...

When the CROSSCORR= option is used, PROC ARIMA prints a plot of the cross-correlation function for each variable in the CROSSCORR= list. This plot is similar in format to the other correlation plots, ...

A plot of the correlation function of a given DNA sequence has certain characteristic features common to almost all organisms. One common feature is that the correlation values at distances that ...
