1. ### Marginalisation of a parameter

Hi everyone, I have a problem with the marginalisation concept. I have a matrix (NxM), where: N refers to the models I tested; M refers to the parameters of each model (i.e., all models have the same M parameters (mass, age, etc., they refer to galaxy properties). Because I have N models I...
2. ### Convolution of two probabilities (non-independent)

I was wondering if the following is true, where * denotes convolution: p(A|C,D) = p(A|B) * p(B|C,D). Basically, I want to know if convolution will marginalize out B. My intuition says this is correct, but I'm not entirely certain. Thank you. Josh
