The computation of the Nth Fibonacci number in this function uses the formula obtained from solving the recurrence relation $$F_{n} = F_{n-1} + F_{n-2},$$ which translates to the equation, $x^{n} = x^{n-1} + x^{n-2}$, and then to $x^2 = x + 1$. The two solutions to the latter equation are $\phi$ and $\psi$, where $$\phi=\frac{1+\sqrt{5}}{2}, \qquad \psi=\frac{1-\sqrt{5}}{2}.$$

This eventually leads to the formula used in this function, $$F_{n} =\frac{\phi^{n} - \psi^{n}}{\sqrt{5}}.$$

$$\sigma = \sqrt{\frac{Z}{n} \sum \textstyle \frac{1}{2} \displaystyle \left[ \left( \log \frac{H_i}{L_i}\right)^2 - \left(2 \log 2 - 1 \right) \left( \log \frac{C_i}{O_i}\right)^2 \right]}$$
