The main research techniques include time series analysis and cross section analysis 采用的主要实证研究方法有:时间序列分析和横截面分析。
In this paper , a generalized finite - element - based cross - sectional analysis for nonhomogenous , initially curved and twisted , anisotropic grp blades is formulated from geometrically nonlinear , three - dimensional ( 3 - d ) elasticity 摘要针对非均匀的、初始弯扭的各向异性玻璃钢叶片,由几何非线性的3维弹性理论导出了常规的有限单元横截面分析公式。
The analytical approaches involved in the dissertation includes cross section analysis 、 time series regression 、 step by step regression and contrast analysis , the following technologies also are applied , including computerizing lower partial moments ( lpm ) with matlab , processing revenue data with excel , regression analysis with eviews 主要运用横截面分析、时间序列回归、逐步回归和对比分析方法,还用到matlab编程计算下偏矩风险值, excel处理收益数据, eviews回归分析。
First , using daily trade data , we measure the mid - term liquidity of individual stock , and carry out cross - section analysis for it . we discover individual liquidity do not have notable discrepancy in different area , sector and size , but the interactive factor of sector and size have notable influence in individual liquidity . then using the 5 minutes intraday data for measuring the individual short - term liquidity , 首先利用日交易数据对个股中期流动性指标进行了度量与横截面分析,发现个股日流动性在地区之间不存在显著的差异,不同行业、不同规模之间也不存在显著差异,但行业和规模的交互因素对流动性的影响比较显著。
