Square Root Jensen-Shannon Divergence

Hi,

I saw Square Root Jensen-Shannon Divergence as one of the calculator for dist.shared, but I’m not sure what does it do

Let x be the relative abundances of one sample and y be the relative abundances of the other and m be the average relative abundances of the 2 samples.

JSD(x,y)= sqrt(1/2 KLD(x,m)+ 1/2 KLD(y,m))

Does it square root transform the data using the relative abundance instead of sequence abundance?

Thanks,
Soon

pretty sure it operates on the relative abundance rather than the raw abundance.
