Conteúdo: 	We attempt to identify the number of underlying physical phenomena behind tomato lateral root initation by using a normal mixture distribution coupled with the Box-Cox power transformation. An initial analysis of the data suggested the possibility of two (possibly more) subpopulations, but upon taking reciprocals, the data appear to be very nearly Gaussian. A simulation study explore the possibility of erroneously detecting a second subpopulation by fiting data which are improperly scaled. A power calculation suggests that only unrealistically large sample sizes can detect the unbalanced mixtures one might expect with data of this type.
