#DeltaF
Or! You calculate Johnson's DeltaF and do the same thing.

F1 ~ ... + offset(log(DeltaF)), family = lognormal

DeltaF normalization involves F1/DeltaF, but that's the same as log(F1) - log(DeltaF).
so, if you calculate mean(log(f1, f2, f3)) for each speaker, and then fit a brms model with the original formants like F1 ~ whatever + offset(logmean), and family = lognormal, that's just Neary normalization!

I spoke with an economist who was used the formula:

deltaT = k * deltaF / (1 - g),

and assumed a normal distribution to represent uncertainty in g. Of course, this blows up as g ==> 1.

I said, "Climate scientists wouldn't use this formula with an assumption of normality on uncertainty in g."
