Inference on the Markowitz portfolio.

Suppose *x* is a *p*-vector of returns of some assets with expected
value *mu* and covariance *Sigma*. The
*Markowitz Portfolio* is the portfolio
*w = Sigma^-1 mu*. Scale multiples of this portfolio
solve various portfolio optimization problems, among them

*argmax{ (mu'w - r0) / sqrt(w'Sigma w) :
w'Sigma w <= R^2}*

This packages supports various statistical tests around the elements of the Markowitz Portfolio, and its Sharpe ratio, including the possibility of hedging, and scalar conditional heteroskedasticity and conditional expectation.
