This method employs periodic orthogonal polynomials to fit observations, and the analysis of variance (ANOVA) statistic to evaluate the quality of the fit. This method was proposed by Schwarzenberg-Czerny1. It strongly improves peak detection sensitivity and damps alias periods.

Peranso implements the algorithm a described by Schwarzenberg-Czerny1.

The ANOVA dialog box is similar to the Lomb-Scargle dialog box. Prominent periods of the Period Window appear as peaks.
