Title: Overview of Likelihood-Based Inference

Abstract: Obtaining a confidence region or a performing significance test of a parameter based on the likelihood function is commonly used in statistics.  Professor Pek in last year’s presentation introduced two likelihood-based methods: Wald method (based on the maximum likelihood estimate of the parameter) and Wilks method (likelihood ratio method).  In this talk, the accuracy of these two methods is examined.  When the parameter of interest is a scalar parameter, a special way of combining the Wald method and the Wilks method is proposed.  This proposed method gives extremely accurate inference results even when the sample size is extremely small.
