TWO METHODS FOR DEFUZZIFICATION OF NUISANCE PARAMETER

The present study seeks the notion of estimation with a nuisance parameter. Tow methods are suggested for using the fuzzy knowledge of the nuisance parameter. In the first method, we calculate a defuzzified value of the parameter and replace it instead of the parameter. In the second method, the authors deffuzify the cumulative distribution function (cdf) of the random variable, X, as a function of the fuzzy parameter. At the end, we compare these two methods.
