The correlation between factors and land use change is discussed and multivariable regression model is set up . by means of standardized regression coefficient of the model , impact of main driving forces on arable land change is analyzed quantitatively 根據(jù)驅(qū)動(dòng)因子與土地利用變化關(guān)系的分析,提出表征縣域土地利用變化驅(qū)動(dòng)因子的指標(biāo)體系,分析了二者的相關(guān)關(guān)系,建立了多元回歸模型,并以其標(biāo)準(zhǔn)回歸系數(shù)為指標(biāo)定量分析了驅(qū)動(dòng)因子對(duì)耕地變化的影響。
We discussed four common outlier tests in pls regression , included partial f test , residual plot and normal quantile plot , latent variables plot ( tit plot ) , contribution plot of variables to latent variables . among these techniques , the first and second are used frequently in ordinal multiple multivariable regression 實(shí)例一的資料來(lái)自于衛(wèi)生管理研究,主要用于偏最小二乘回歸與一般最小二乘回歸之間的優(yōu)劣比較,以及偏最小二乘回歸離群點(diǎn)檢測(cè)方法的實(shí)際運(yùn)用。
