Pairwise linear regression
WebI was wondering what would be the difference between using the pairwise versus the listwise option in a multiple regression? I have a dependent variable (reaction time) and several predictors (accuracy, and 4 measures corresponding to anxiety & depression). WebHere is an easier approach using ggplot2. require (ggplot2) qplot (offer, demand, group = offer > 22.4, geom = c ('point', 'smooth'), method = 'lm', se = F, data = dat) EDIT. I would also recommend taking a look at this package segmented which supports automatic detection and estimation of segmented regression models. UPDATE:
