[R-sig-eco] sd normalmixEM

Hi! I am using normalmixEM to fit a mixture of normal distributions. I dont see an estimation of the standard deviation of the parameters. Any idea? thanks in advance MAriela [[alternative HTML version deleted]] ___ R-sig-ecology mailing list

Have you tried taking a look at the mclust package? It's quite flexible, and obtains these statistics. Phil On 5/9/2014 8:30 AM, Mariela Sued wrote: Hi! I am using normalmixEM to fit a mixture of normal distributions. I dont see an estimation of the standard deviation of the parameters.

Hi Jari, Thanks so much for your clarification and expansion of Gavin's comments. I was confused by the application of bootstrapping to a function that is already using a permutation procedure, but I see now that bootstrapping the regression coefficients would operate independently of adonis'

The output from the normalmixEM function returns mu and sigma, mean and std dev. of the distributions, a simple boot.se() of these output estimates will generate the standard error of the mean and stand. dev. Best, Jason Jason G. Romine,

Rafter, The permutation test goes nowhere near the coefficients. IIRC it works on the sum of squares decomposition directly. Jari has already passed on more info about the bootstrapping idea. Basically the boot package has functions that will apply your function to bootstrap samples of the
