The latter cannot be included otherwise it looks like E = cXbar and Ybar by hypothesis is fixed. For example, Y = f(X,Xbar) where the function includes an additive term aX, an interactive term bXXbar but no additive term cXbar. Here you might say Xbar directly influences Y. There is frequency dependent selection so Xbar must influence Y (individual fitness) not through Ybar (by definition fixed) but through interaction with Xbar. Consider a case in evolutionary biology known as soft selection. Wesley Anderson posted on Tuesday, Ma12:28 pm Or, do you see a need for something different? This is directly influencing the observed Y.
I would say that when Xbar influences the between-level latent part of Y, where the observed Y is decomposed into 2 uncorrelated parts, Is there no way that Xbar can be modeled to directly cause Y? I am merely making sure I understand what's going on correctly.īengt O. Could you elaborate please? Also, I am not trying to discover a limitation in the methods used in Mplus. I am not clear how the correlation or lack thereof (perhaps you mean after statistically control) between these two variables makes it the case that Xbar can or cannot be modeled to cause Y directly. Wesley Anderson posted on Tuesday, Ma11:18 amīut of course X and Xbar are correlated if Xbar is the mean of X in a group. But this doesn't seem to me a limitation. No, because the variables on the 2 levels are taken to be uncorrelated, just like in regular random effects anova. Is there no way that Xbar can be modeled to directly cause Y? I appreciate it.īengt O.
When you use a random-slope model you assume Xbar causes Y through the partial regression coefficient of Y on X. When you use a random-intercept model you assume Xbar causes Y through Ybar. And another response variable measured on persons Y. Say you have two variables X and Xbar, the former measured on persons and the latter measured on groups of persons.

So I swapped all the vertical/horizontal and x/y pairs I could find, and transposed the tables, but the result is wrong: it kinda seem to work but only the first seven rows are shown, with huge spacing between them.
#Xbar and ybar software
It is the running time and memory consumption of a set of software tools over different sets of input data. I had a group of two ybar stacked plots which worked quite well, but I needed to convert it to a similar configuration of two xbar stacked plots.
