...present. Below is an example of what I mean. In model2, the variable z is added, which is hypothesized to partly explain the effect of x. Indeed, the effect of x decreases in model2, compared to model1. What I want to find out, is if this decrease is statistically significant. Many thanks, Rense x <- c(1,1,1,1,1,2,2,2,2,2,3,4,4,4,5) z <- c(2,2,2,2,2,2,2,2,3,3,3,3,4,4,5) y <- c(1,2,2,2,3,3,3,3,4,4,4,5,5,5,5) model1 <- lm(y~x) model2 <- lm(y~x+z) [[alternative HTML version deleted]]
