A new periodogram was proposed using one-way analysis of variance (ANOVA),
termed ANOVA periodogram, in order to reveal a precise significant periodic
ity. Thirty 3-day complex computer-simulated time series with known periodi
city (24 h) and three 2-h data-missing occurring periodically (23 h, 20 min
) were used to compare the ANOVA periodogram with Enright's one. In results
, the ANOVA periodogram was superior to Enright's periodogram in the accura
cy of assessing the major periodicity.
