In the command window output when using fitdist there are vectors in connection to the parameter values that look like they might contain confidence intervals (a vector containing two values for each parameter). However they are not mentioned at all in the documentation for fitdist and when I look among the properties for the created probability distribution they are nowhere to be found. What are they? They need to be mentioned in the documentation. For example, refer to MATLABs own example code for using fitdist (run following line in MATLAB command window): openExample('stats/FitaNormalDistributiontoDataExample')

load hospital x = hospital.Weight; pd = fitdist(x,'Normal') pd_mean = mean(pd) % Function References pd_std = std(pd) pd_ci = paramci(pd) pd_mean = pd.mean % Structure References pd_std = pd.std pd_ci = pd.paramci
The information is inconveniently buried in the documentation, but it is all available. Additional documentation, including that necessary to change the confidence interval probabilities from the default 95%, is available in the paramci page.
