Webthe Greenhouse-Geisser corrected results or; the Huyn-Feldt corrected results. Precisely which depends on the Greenhouse-Geisser epsilon. Epsilon is the Greek letter e written as ε. It estimates to which extent sphericity holds. For this example, ε = 0.840-a modest violation of sphericity. If ε > 0.75, we report the Huyn-Feldt corrected ... WebGreenhouse-Geisser correction is used when sphericity is violated The assumption of sphericity is often not met when conducting repeated-measures ANOVA analyses. For practical purposes, the Greenhouse-Geisser correction is often used to correct for the violation of the assumption of sphericity.
