Stepwise discriminant analysis used for discriminant sediment source of the south of the yellow sea 南黃海表層沉積物物質(zhì)來源的逐步判別分析
Stepwise discriminant analysis was performed to obtain risk factors of caa based on clinical and early laboratory data 我們先以單變數(shù)統(tǒng)計方法來檢驗十六個臨床和實驗變數(shù),發(fā)現(xiàn)在兩群中只有白血球和c -反應蛋白質(zhì)具有統(tǒng)計上之顯著差異。
This paper adopts factor analysis and stepwise discriminant analysis , based on financial and non - financial factors , to build the sme credit assessment indicator system whereby this paper builds the lda model and logit model . finally this paper empirically tests these models using relating data 本文采用因子分析和逐步判別分析相結(jié)合的方法,在綜合考慮財務和非財務因素的基礎上,建立適合于中小企業(yè)信用評估的指標體系,分別構(gòu)建了基于該指標體系的線型判別模型和logit回歸模型,并運用國內(nèi)的相關(guān)數(shù)據(jù)進行了實證。
