The main aim of the study is to assess relationship between dependent variable GDP Independent variables agriculture, industry, service sector by using n-variable Regression Model at initial condition. Design/Methodology/Approach: an application condition analyze situation along with reasons not beco...

We study the consequences of measurement error in dependent variable random‐coefficients models, focusing on particular case quantile regression. The popular regression estimator Koenker and Bassett (1978) is biased if there an additive term. Approaching this problem as errors‐in‐variables where suffers from classical error, we present a sieve maximum likelihood approach that robust to left‐han...

Peer effect is a potential determinant of individual weight gain that has drawn considerable attention recently. The presence of peer effect implies that policies targeted at changing bodyweight can have enhanced effectiveness through a multiplier effect. This study aims to measure the peer effects on adolescent bodyweight in China. Using the small community nature of the rural sample of the wa...
