You've probably noticed certain things that have a clear relationship with one another. For example, the amount of petrol your car uses increases along with the number of kilometres you drive. Or, if ...

In the first case, there is a strong upward-sloping relationship between X and Y; in the second case, no apparent relationship; in the third case, a strong downward-sloping relationship. Note the ...

This example defines modules to compute correlation coefficients between numeric variables and standardized values for a set of data. /* Module to compute correlations */ start corr; n=nrow(x); /* ...

NOTE: F Statistic for Roy's Greatest Root is an upper bound. As Output 20.1.2 shows, the first canonical correlation is 0.7956, which would appear to be substantially larger than any of the ...

The correlation function is a useful signal-analysis tool that engineers often overlook. Its formidable equation, which you have probably not thought about since your undergraduate signals and systems ...
