WebFits a two parameter Weibull distribution (alpha,beta) to the data provided. Notes If the fitting process encounters a problem a warning will be printed. This may be caused by the chosen distribution being a very poor fit to the data or the data being heavily censored. If a warning is printed, consider trying a different optimizer.
