F= fitmethis(X) finds the distribution that best fits data in vector X among all distributions available in MATLAB's function MLE. Either continuous or discrete distributions are used based on user input or the type of data supplied (see below). A non-parametric (kernel) fitting is added for "difficult" data.
The function returns a structure array with fields:
name: name of the distribution (see HELP MLE for a list)
par: vector of parameter estimates (1, 2 or 3 values)
ci: matrix of confidence limits, one column per parameter
LL: Log-Likelihood of the data
aic: Akaike Information Criterion
Optional arguments can be specified as name/value pairs (see help).
