MEDIATION ANALYSIS WITH R
I have tried to do a mediation analysis In my dataset I did not use a treatment. If i write treatment = NULL the program sends me back a error. How i can do this? R> model.m <- lm(job_seek ~ treat + depress1 + econ_hard + sex + age + occp + marital + nonwhite + educ + income, data = jobs) R> model.y <- lm(depress2 ~ treat + job_seek + depress1 + econ_hard + sex + age + occp + marital + nonwhite + educ + income, data = jobs) R> out.1 <- mediate(model.m, model.y, sims = 1000, boot = TRUE, treat = "treat", mediator = "job_seek") R> out.2 <- mediate(model.m, model.y, sims = 1000, treat = "treat", mediator = "job_seek") thank you -- ste -- ste [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
