Testing statistical hypotheses with vague data

  title={Testing statistical hypotheses with vague data},

  journal={Fuzzy Sets and Systems},
A de nition of fuzzy test for testing statistical hypotheses with vague data is proposed. Then the general method for the construction of fuzzy tests for hypotheses concerning an unknown parameter against one-sided or two-sided alternative hypotheses is shown. This fuzzy test, contrary to the classical approach, leads not to the binary decision: to reject or to accept given null hypothesis, but to a fuzzy decision showing a grade of acceptability of the null and the alternative hypothesis… CONTINUE READING
