Many asymptotic results for kernel-based estimators were established under some smoothness assumption on density. For cases where smoothness assumptions that are used to derive unbiasedness or asymptotic rate may not hold we propose a combined estimator that could lead to…

Radio Frequency Identification Technology (RFID) that arose from World War II developments has become one of the most attractive management tools to the business environment yet has faced scarce current applicability. This study analyses the opinion of specialists engaged in…
