Research Interests

Kernel density estimation: The Hellinger Distance as a measure of error for the estimation. The kernel contrasts. The Kernel density estimators of functions of observations. The nonparametric methods to estimate the hazard function and the mean residual life function.
Life Testing: Testing exponentiality against IFR, NBU, NBUE, and HNBU. Compare life with its equilibrium form.
