data('return')
A data.frame with 142 observations on 12 variables:
roe: return on equity, 1990
rok: return on capital, 1990
dkr: debt/capital, 1990
eps: earnings per share, 1990
netinc: net income, 1990 (mills.)
sp90: stock price, end 1990
sp94: stock price, end 1994
salary: CEO salary, 1990 (thous.)
return: percent change s.p., 90-94
lsalary: log(salary)
lsp90: log(sp90)
lnetinc: log(netinc)
More can be done with this data set. Recently, I discovered that lsp90 does appear to predict return (and the log of the 1990 stock price works better than sp90). I am a little suspicious, but you could use the negative coefficient on lsp90 to illustrate “reversion to the mean.”
