查询词典 correlation function

As the representative of the northern Loess Plateau gully region, the soil quality under different cultivation length of the orchard in Changwu county was studied. Using partial correlation coefficient to determine the weight, combined with evaluation of membership Sanction to evaluate soil quality levels of the area, the trend of orchard soil quality under different cultivation years was analyzed. The results showed that the IFI values of orchard soil were between 0.22 and 0.70, 27% of them reached the second soil quality standards, 64% reached a third-level soil quality standards, 9% met the fourth standards of soil quality.

The statistical difference of proinsulin rather than HOMA index was found among the patients of various Gensini's score group (Gensini's score was examined as a categorical variable classified by tertile values) and significantly stenosed vessels group by means of the results of analysis of covariate variance after adjusting for age, sex and body mass index (p＜0.05), and the partial correlation coefficient between proinsulin level and Gensini's score, the number of significantly stenosed vessels after adjusting for age, sex and body mass index was 0.3156 (P＜0.01) and 0.2752 (P＜0.05) respectively. Multivariate linear regression analysis indicated that the level of proinsulin was positively correlated with the Gensini's score (P＜0.01). The results of multivariate stepwise Logistic indicated that the proinsulin was the independent risk factor for the coronary heart disease, and the odds ratio (95％ confidence interval) was 2.268 (1.253～4.105)(P=0.007), however, the HOMA was refused by the final model.
