A General Approach to Causal Mediation Analysis

approach that overcomes these limitations. Our approach is general because it offers the deÞnition, identiÞcation, estimation, and sensitivity analysis of causal mediation effects without reference to any speciÞc statistical model. Further, our approach explicitly links these 4 elements closely together within a single framework.

Second a course on statistical physics certainly has to make the connection to thermo-dynamics. Thermodynamics can be quite cubersome and hard to digest at times, so a pedagogical approach is highly appreciated by most students. Here I am strongly motivated by the axiomatic and geometrical approach to thermodynamics as layed out

Fitting Linear Mixed-Effects Models using lme4

In a linear model the distribution of Y is multivariate normal, Y ∼ N(Xβ +o,σ2W−1), (1) where n is the dimension of the response vector, W is a diagonal matrix of known prior weights, β is a p-dimensional coeﬃcient vector, X is an n×p model matrix, and o is a vector of known prior oﬀset terms. The parameters of the model are the ...
