Compute a Bayes Factor for the comparison of independent variances

1	indepvarBF(x, y, rscale = "medium")

`x`	first continuous variable
`y`	second continuous variable
`rscale`	The prior width specifying the alternative hypothesis, passed to `oneWayAOV.Fstat`

This function realizes a test of independent variances by converting the F value from a Levene test to a Bayes Factor using the function oneWayAOV.Fstat.

The Bayes factor quantifying the degree to which the alternative hypothesis is favored over the null hypothesis

As stated it the documentation to oneWayAOV.Fstat, this method should only be used with F values obtained from balanced designs (i.e., the groups should have equal size).

# True different variances:
indepvarBF(rnorm(100, mean = 100, sd = 15), rnorm(100, mean = 100, sd = 20))
# True same variances: 
indepvarBF(rnorm(100, mean = 100, sd = 15), rnorm(100, mean = 100, sd = 15))
