Theory and application of multivariate methods (dependence)
In our data matrix we have one variable of particular interest and we wish to see how it is affected by movements in a single explanatory variable. For example, the variable we might be interested in is Sales in £mn and we may wish to know how it is affected by advertising expenditure in £000's. The rows of our data matrix may consist of the last seven years of data for these two variables.
