In this section, we will dive into the technical implementation of a multiple linear regression model using the R programming language. We will use the customer churn data set from DataCamp’s workspace to estimate the customer value. What do we mean by customer value? Basically, it determines...
Our model now has two predictors in it, so it takes this generalized form: y=β0+β1x1+β2x2 Specifically, our model is: lifeExpF=30.7+11×logppgdp+0.023×pctUrban Multiple regression is a little trickier to interpret than simple regression. Our model says that if we were to hold all...

In this case, we can ask for the coefficient value of weight against CO2, and for volume against CO2. The answer(s) we get tells us what would happen if we increase, or decrease, one of the independent values. Example Print the coefficient values of the regression object: ...
Following this theoretical framework, the book explores applications involving the Dunnett test, Tukey's all pairwise comparisons, and general multiple contrast tests for standard regression models, mixed-effects models, and parametric survival models. The last chapter reviews other multiple comparison ...

we model a change from a plateau with strong positive AR(2) residuals to a slope with medium AR(1) residuals. These data were simulated withmcp(see simulation code:mcp_example("ar")$call) and the generating values are in thesimcolumn. You can also do regression on the AR coefficients ...
Extant research suggests that workplace ostracism has a detrimental impact on the outcomes of employees. However, very little is known about the impact of workplace ostracism on sleep quality. Therefore, this study aimed to address this gap in the literature. By employing the extended stressor-det...
