Freeny's Revenue Data


Freeny's data on quarterly revenue and explanatory variables.




There are three ‘freeny’ data sets.

freeny.y is a time series with 39 observations on quarterly revenue from (1962,2Q) to (1971,4Q).

freeny.x is a matrix of explanatory variables. The columns are freeny.y lagged 1 quarter, price index, income level, and market potential.

Finally, freeny is a data frame with variables y, lag.quarterly.revenue, price.index, income.level, and market.potential obtained from the above two data objects.
