查询词典 multivariate analysis

Canonical Correlation Analysis is a important research subject of multivariate statistical analysis.

典型相关分析是多元统计分析的一个重要研究课题。

In order to ensure the reliability and accuracy of theoretical analysis, we use empirical analysis on the market data. At first, we make multivariate statistical regression on the financial indicators, including the day-to-day operating conditions, the stock market performance, and single-stock risk in a fluctuation cycle. On the basis of control variables, we then examine the direct impact of governance indicators and the indirect impact (the cross-variable regression of financial and governance).

Study on the driving forces of land use/cover temporal-spatial change. On the basis of the systematical study on natural and social-ecomic factors including climate, population, technology and affluence status etc. during the past 50 years in this area, the multivariate statistics simulation models of LUCC were developed for two periods of 1950's-1980's and 1986-2000 respectively. Then, the Thiesson polygon method was used to the spatial allocation of soci-economic factors, thereby the spatial relationship between land use degree change and socieconomic factor variation was detected within GIS. Based on the analysis of the integrative characters in different geographical divisions, the electivity index was employed to describe the possible impacts of the natural landscape structure on spatial differentiation of land use transition. At last, correlation analysis between major roads and the distribution of land use change was made.
