Multiple linear regression analyses were used to examine the mediation effect of the psychosocial factors on health-related quality of life. Results showed that stigma and social support did not have direct effects, but indirect effects on health-related quality of life through a full mediation ...
Also, at present, multiple regression models such as generalized linear and additive models provide a greater choice of error distributions (e.g., Normal, gamma, negative binomial) and functional forms. Yet, the specifics of mediation analysis based on such models are to be clarified (Wang et...
Fig. 2: Associations between individual toxicants and gestational age at delivery (in weeks) estimated by weighted multiple linear regression (N=161). Models adjusted for specific gravity, maternal age, race, education, health insurance, and BMI at the initial study visit. Toxicants are organized...

2) Also, should I be concerned that when I run the model as a multiple linear regression (in SPSS) and include the interaction term (m1Xm2_2) I get a VIF > 5 for the m2_2 coefficient? 3) My understanding is that the traditional approach taken to deal with multicollinearity induced ...
If multiple Y variables are considered, multivariate methods should be used. Software packages with SEM utilities can simultaneously estimate Equations 1, 2, and 3 (rather than having to estimate individual regression models) and can handle multivariate mediation models adeptly. To get a better ...
For each analysis, the overall significance of the regression model was confirmed by the ANOVA F-statistic (and its associated p-value) provided by SPSS multiple linear regression function, which is a ratio of the mean square regression to the mean square error. 2.7 Mediation analysis Subsequent...
Data analysis was performed using Stata software version 12.1 (Stata Corp, College Station, TX, USA). C-reactive protein and triglycerides were log-transformed because of their asymmetric distribution. Analysis of variance (ANOVA) was used to compare means. Multiple linear regression was carried out...
multiple linear regression was conducted to investigate the specific associations of BMI, life satisfaction, and cognitive function with symptoms of anxiety, separately, Adjustments for age, gender, education level, and TONI-4 index score were included in the multiple linear regression model to exclude...
