One case of a high correlation coefficient close to that limit was identified--a positive correlation of 0.78 between holdings of government securities (TPF) and concentration of government bonds in the portfolio (GOV), which can be explained by the low representativeness of state and municipal bonds.

Also, as TPFs must be positive valued, one notes that
Theorem 1 and the linear nature of summation give that TPFs easily can be combined to produce other TPFs.
The next theorem uses Theorem 6 to show that certain powers of TPFs are themselves TPFs while certain powers of non-TPF functions will not be TPFs.
As previously noted, [arc.C] erepanova (1963; 1966) proved that each of the functions f(x) = cos(x/2) and [cos.sup.2](x/2) is a TPF. In this paper the authors extend these results to show that functions of the form f(x) = [cos.sup.s](x/k) are TPFs for integers k [greater than or equal to] 2 and real numbers 0 [less than or equal to] s [less than or equal to] k.
Having proved that functions of the form f(x) = [cos.sup.k](x/k) are TPFs for integers k [greater than or equal to] 2, the authors will now expand this result to include all functions of the form f(x) = [cos.sup.s](x/k) for any integer k [greater than or equal to] 2 and any real number s, with 0 [less than or equal to] s [less than or equal to] k.
It is noted for integers k [greater than or equal to] 2 and numbers s > k that functions of the form f(x) = [cos.sup.s](x/k) sometimes are TPFs but not always.
It has been asked (see Aassila (2005)) if functions of the form f(x) = [sin.sup.s](x/2) would be TPFs for s > 0.
From statement (13) see that for s > 0, functions of the form f(x) = [sin.sup.s](x/2) cannot be TPFs.
