%description
Implements two algorithms of detecting Bull and Bear markets in stock
prices: the algorithm of Pagan and Sossounov (2002, <doi:10.1002/jae.664>)
and the algorithm of Lunde and Timmermann (2004,
<doi:10.1198/073500104000000136>). The package also contains functions for
printing out the dating of the Bull and Bear states of the market, the
descriptive statistics of the states, and functions for plotting the
results. For the sake of convenience, the package includes the monthly and
daily data on the prices (not adjusted for dividends) of the S&P 500 stock
market index.
