Description
Summary:The computation of modified Allan variance directly from its definition is much more expensive than the computation of conventional Allan variance. A simple observation shows that a program for computing the conventional Allan variance from second differences of phase residuals can easily be embellished to compute the modified Allan variance with only a small increase in code, memory, and time.< >
