This final project discusses two regression estimators for the average of population in random sampling by using quartiles, deciles and cofficient of variation from additional variables written by Subzar et al. [Journal of Reliability and Statistical Studies, 10 (2017), 65–82]. The estimator is bias estimator. Furthermore, the two estimators are compared with the ratio estimator through …

This final project discusses a method for solving a quadratic programming problems with interval coefficient. The method used is extenstion of Wolfe’s method. Wolfe modified the simplex method to solve quadratic programming problem by adding conditions of the Karush-Kuhn-Tucker and transform quadratic programming problems with interval coefficient into two linear programming problems mod…
This final project discusses incomplete tribonacci-Lucas numbers and polynomials. Furthermore, the recurrence relations of homogeneous and nonhomogeneous and the sum of incomplete tribonacci-Lucas number and polynomials are also discussed. This is a review of some parts of Yilmaz and Tascara’s paper [Advances in Applied Clifford Algebras, 25 (2015), 741-753]. Keywords: Tribonacci-Lucas n…
This final project discusses two ratio estimator for the population mean in simple random sampling using quartile information, deciles and coefficient of skewness of an auxiliary variable which are assumed to be able to provide information to the characters examined. The two estimators are biased estimators, then the mean square errors (MSE) of the two estimators are obtained by Taylor ser…
