A higher R-squared value indicates a more useful beta value. For example, if a stock or fund has an R-squared value close to 100%, but has a beta below 1, it most likely offers higher risk-adjusted returns. Definition 4.1.1 THe Position Vector. Let P = (p1, ⋯, pn) be the coordinates of a point in Rn. Then the vector → 0P with its tail at 0 = (0, ⋯, 0) and its tip at P is called the position vector of the point P. We write → 0P = [p1 ⋮ pn] For this reason we may write both P = (p1, ⋯, pn) ∈ Rn and → 0P = [p1⋯pn]T ∈ Rn.In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y.
