S CHOOL OF M ATHEMATICS ‚ S TATISTICS AND O PERATIONS R ESEARCH STAT 392 Tutorial – Ratio and Regression Estimation 1. Regression Estimation (from Lohr‚ Ex 3.6.4) Foresters want to estimate the average age of tress in a stand. Determining age is cumbersome because one needs to count the tree rings on a core taken from the tree. In general‚ though‚ the older the tree‚ the larger the diameter‚ and diameter is easy to measure. The foresters measure the diameter of all 1132 tress and find that

The simple regression model (SRM) is model for association in the population between an explanatory variable X and response Y. The SRM states that these averages align on a line with intercept β0 and slope β1: µy|x = E(Y|X = x) = β0 + β1x Deviation from the Mean The deviation of observed responses around the conditional means µy|x are called errors (ε). The error’s equation: ε = y - µy|x Errors can be positive or negative‚ depending on whether data lie above (positive) or below the conditional

you cannot consult the regression R2 because (a) ln(Y) may be negative for 0 < Y < 1. (b) the TSS are not measured in the same units between the two models. (c) the slope no longer indicates the effect of a unit change of X on Y in the log-linear model. (d) the regression R2 can be greater than one in the second model. 1 (v) The exponential function (a) is the inverse of the natural logarithm function.

ABSTRACT Internal logistics is one of the most important sections within enterprises‚ especially in the large manufacturing companies. It manages‚ arranges‚ plans and delivers the finished products. It is an indispensable part of the supply chain‚ as well as reflects the result of implementation company strategy. This study focuses on finding the possible ways to improve the operation process of Nokia-China internal logistics by looking into Nokia-China’s internal logistics in Dongguan Branch-

REVERSE LOGISTICS: CHALLENGES AND ISSUES FACED BY THE MAJOR RETAIL PLAYERS IN THE UK. INTRODUCTION: “In the sweat of your face you shall eat bread till you return to the ground‚ for out of it you were taken; For dust you are‚ And to dust you shall return.” Genesis 3:19. Effective and efficient management of product returns is an intriguing practical and research question. Growing green concerns and advancement of reverse logistics (RL) concepts and practices make it all the more relevant
