In statistics, one-way analysis of variance (or one-way ANOVA) is a technique to compare whether two or more samples' means are significantly different (using the F distribution).
The KL-D from the free energy expression maximizes the probability mass of the q-distribution that overlaps with the p-distribution, which unfortunately can result in mode-seeking behaviour. The "reconstruction" term is the remainder of the free energy expression, and requires a sampling approximation to compute its expectation value.
Rather than making journal articles accessible through a subscription business model, all academic publications could be made free to read and published with some other cost-recovery model, such as publication charges, subsidies, or charging subscriptions only for the print edition, with the online edition gratis or "free to read".
