文中采用Khandelwal提出的Nested-Logit模型测度2001—2015年中国等15个主要林产品贸易强国的出口林产品质量指数，随后采用面板数据模型分析影响出口林产品质量的主要因素。结果显示：发展中国家出口林产品质量发展态势相对一致，总体呈现为稳步增长；发达国家出口林产品质量发展趋势分化明显，存在缓慢增长、小幅波动、缓慢下降等几种态势；国家间出口林产品质量影响因素存在较大差异，发展中国家...
基于Nested Logit模型的共享单车选择行为研究
城市交通 共享单车 共享单车选择行为 Nested Logit
2018/11/16
近两年来，共享单车迅速发展，已有研究较少从微观角度来阐释共享单车的选择行为.本文基于随机效用理论，构建Nested Logit模型，选取出行目的、接驳时间、在车时间、停车时间、费用等出行特征变量，选取下雨(雪)、空气质量、气温、风力等级等天气状况变量，选取年龄、性别、收入等社会经济变量作为效用函数的特征变量，采用D-optimal法设计问卷，在济南市开展共享单车实证调查.基于收集到的样本进行参数标...
SEARCHING REMOTELY SENSED IMAGES FOR MEANINGFUL NESTED GESTALTEN
Perceptual grouping Symmetry Urban structure recognition

Usual workflows for production, archiving, dissemination and use of Earth observation images (both aerial and from remote sensing satellites) pose big interoperability problems, as for example: non-al...
Global Stabilization for Feedforward Nonlinear System Based on Nested Saturated Control
Feedforward nonlinear system nested saturated control global stabilization
2009/9/28
In this paper, we discuss global stabilization procedure to make some classes of feedforward nonlinear systems be convergent. Our stabilizer consists of a nested saturation function, which is a nonlin...
摘要: This paper presents a new approximate algorithm Nested Queue-Jumping Algorithm (NQJA) to solve traveling salesman problem. The proposed algorithm incorporates the thoughts of heuristic algori...
A NOVEL FEATURE EXTRACTION METHOD FOR ISOLATED WORD RECOGNITION BASED ON NESTED TEMPORAL AVERAGING
Speech recognition Pattern classification Neural Networks Support Vector Machines
2010/1/12
A novel preprocessing method is proposed. It has a reduced complexity and therefore is aimed to be used in low power, VLSI implemented, speech recognizers. Our algorithm extracts a feature vector made...
