Goodness-of-Fit Test: Khmaladze Transformation vs Empirical Likelihood
This paper compares two asymptotic distribution free methods for
goodness-of-fit test of one sample of location-scale family: Khmaladze
transformation and empirical likelihood methods. The comparison is made from
the perspective of empirical level and power obtained from simulations. When
testing for normal and logistic null distributions, we try various alternative
distributions and find that Khmaladze transformation method has better power in
most cases. R-package which was used for the simulation is available online.

A Fast Algorithm for Implementation of Koul's Minimum Distance Estimators and Their Application to Image Segmentation
Minimum distance estimation methodology based on an empirical distribution
function has been popular due to its desirable properties including robustness.
Even though the statistical literature is awash with the research on the
minimum distance estimation, the most of it is confined to the theoretical
findings: only few statisticians conducted research on the application of the
method to real world problems. Through this paper, we extend the domain of
application of this methodology to various applied fields by providing a
solution to a rather challenging and complicated computational problem. The
problem this paper tackles is an image segmentation which has been used in
various fields. We propose a novel method based on the classical minimum
distance estimation theory to solve the image segmentation problem. The
performance of the proposed method is then further elevated by integrating it
with the ``segmenting-together" strategy. We demonstrate that the proposed
method combined with the segmenting-together strategy successfully completes
the segmentation problem when it is applied to the complex, real images such as
magnetic resonance images
Application of the Cramer-von Mises type optimization to a binomial distribution
This paper proposes the novel estimator for the success probability parameter
of a binomial distribution. To that end, we use the Cramer-von Mises type
optimization methodology which has been popular for the parameter estimation in
continuous distributions. Upon obtaining the estimator, desirable properties of
the proposed estimation method such as asymptotic distribution and robustness
are rigorously investigated. Simulation studies demonstrate that the proposed
estimator compares favorably with other well-celebrated estimators
