Extracting confidence interval data from fitdist()
显示 更早的评论
I'm using fitdist() to fit a poisson distribution, which works great, but I'm having trouble locating the confidence interval within the created PoissonDistribution object. The confidence interval gets returned if you enter the distribution object in the command line, but as far as I can tell doesn't exist as a substructure within the distribution. I'm not sure how to extract the confidence interval if I don't know where it is stored. Thanks!
pd = fitdist(a','poisson');
pd =
Poisson distribution
lambda = 0.0166667 [0.000421963, 0.0928607]
pd.lambda
ans =
0.0167

Use the paramci function:
pd_ci = paramci(pd)

this doesnt work for poisson distrubutions anymore?
It seems to work —
data = poissrnd(42, 100, 1);
pd = fitdist(data,'poisson')
pd_ci = paramci(pd)
.

not for makedist, it gives the error regarding Dot indexing is not supported for variables of this type.
