Improved Estimation of Population Mean Using Median and Coefficient of Variation of Auxiliary Variable
This manuscript deals with the estimation of population mean of the variable under study using an improved ratio type estimator utilizing the known values of median and coefficient of variation of auxiliary variable. The expressions for the bias and mean square error (MSE) of the proposed estimator are obtained up to the first order of approximation. The optimum estimator is also obtained for t...
متن کاملStatistically Efficient Estimation Using Population Coding
Coarse codes are widely used throughout the brain to encode sensory and motor variables. Methods designed to interpret these codes, such as population vector analysis, are either inefficient (the variance of the estimate is much larger than the smallest possible variance) or biologically implausible, like maximum likelihood. Moreover, these methods attempt to compute a scalar or vector estimate...
متن کاملSimultaneous estimation and variable selection in median regression using Lasso-type penalty.
We consider the median regression with a LASSO-type penalty term for variable selection. With the fixed number of variables in regression model, a two-stage method is proposed for simultaneous estimation and variable selection where the degree of penalty is adaptively chosen. A Bayesian information criterion type approach is proposed and used to obtain a data-driven procedure which is proved to...
متن کاملEfficient Channel Estimation of OFDM System using Linear Estimators and Median Filtering
The outperforming stage of wireless communication system need to be developed for reliable delivery of the information. Every wireless communication system has a major influence by the information transferring media (channel). The behavior of wireless channel is quite varying in nature so that the predictions of noises disturbing signals is very crucial task. So the estimation of channel play a...
متن کاملEfficient median estimation for large-scale sensor RFID systems
We consider the median estimation problem in a large-scale sensor augmented RFID system. The large-scale deployment of RFID technology has opened the door to innovative ways to integrate RFID and sensor technology. Sensor-tags are tags that can report over 50 types of physical information to a reader. The traditional way to obtain information from sensor-tags is to query each tag. When the numb...
