When the treatment variable is continuous or a factor with multiple levels, user must specify the values oft1andt0using the 'treat.value' and 'control.value' arguments, respectively. The value oftin the above expressions is set tot0for 'd0', 'z0', etc. and tot1for 'd1', 'z1', etc...
SEM is based on covariances, which are relatively unreliable when estimated from small samples (Kline, 1998). The same problem applies to SEM parameter estimates and chi-square tests of goodness-of-fit. Also, at present, multiple regression models such as generalized linear and additive models ...
Chapter 1 covers linear regression analysis including regression with an interaction, multiple-group analysis, missing data on covariates, and heteroscedasticity modeling. Chapter 2 covers mediation analysis with a continuous mediator and a continuous outcome including moderated mediation. Chapter 3 covers sp...
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...
regression from pain onto fatigue tells us if aa is significant; multiple linear regression from pain and fatigue onto well-being tells us if bb and c′c′ are significant; regression from pain onto well-being tells if cc is significant and/or different from c′c′. Paths c’ and b in...

3.2 Regression-based approach for multiple mediators with a continuous outcome Under these assumptions the natural direct and indirect effects can once again be estimated using a parametric regression-based approach. We will use one regression for the outcome Y and a separate regression for each of ...
