Growth of Money Supply Data.
data(growthofmoney)
A multivariate quarterly time series from 1970(2) to 1974(4) with variables
The data was originally studied by Hetzel (1981), the data set is given in Krämer and Sonnberger (1986). Below we replicate a few examples from their book. Some of these results differ more or less seriously and are sometimes parameterized differently.
