This is so very helpful! I have one question. If an exogenous variable does not have a direct effect to an endogenous variable but rather only goes through mediators, is this both the total effect and the total indirect effect? Thank you!!
Thank Prof. Crowson for your very interesting video. I see: total effect = direct effect + indirect effect; however, i wonder this equation is whether right once considering the statistical significance of effects. Specifically, p_value of indirect effect is >0.05, so this effect is not significant (at 95% confidence level) and then should we regard it to estimate the total effect? And which level(s) (e.g. 0.1; 0.05; 0.01; 0.001) should be used in order to test the significance of effects and thus conclude about the relationship between variables? In your video, you guide to manually make equations for calculating total effect of each variable. In fact, there are many exogenous and endogenous variables in a model, possibly resulting in numerous mediated effects and (very) long codes. Is there any ways to make short codes for estimating direct, indirect, total effects for all variables simultaneously? Thank you for reading my questions and look forward to your answers.
Thank you for your sharing, Mike. I am trying to use lavaan for SEM which is containing moderator in my model. Could you share an example about how to do it?
Hi Mike, it seems this code lavaan(model,data=processdata,se="bootstrap") does not work on my version of R studio. but if I use sem( ), instead of lavaan( ), I will get the output.
Hi there. I believe I might have covered this in the first video in this series: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-QP-v6RwsZjY.html Also the third video in this series can be found here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-HvYW_GeHpD8.html Thanks for visiting! Cheers!
