Six transformations viz., , log[log (x + 2)] and log[log (x + k )] were tested for their efficiency in stabilizing variance of Coccus viridis (Green) population counts which followed negative binomial distribution. Only log[log(x + 2)] transformation was found effective in stabilizing variance. This is a new transformation proposed by the authors.
