Multiple comparisons with uncertain number of tests
In metagenomics one typically collects data representing gene/species counts (or their proportion) in an individual. One then performs comparisons for every gene/species in groups of individuals ...

Combining prior on effect size with new effect size estimate (Bayesian)
CONTEXT I am a researcher planning experiments. My goal is to combine a prior on the effect size from prior literature with pilot data. SETUP Assume I have a prior on an effect size, $d \sim N(d_{\...

What does skewed distribution as posterior mean?
I am trying to estimate the values of three unknown parameters in the Ordinary Differential Equation (ODE) using pyMC. Physically, A should be smaller than both B and C. But, given the data and ODE I ...

Avoiding the problem with degrees of freedom using bayesian
Here is classic linear mixed effects regression: $$y_{ij} = \beta_0 + \beta_1 x_{ij} + u_j + \epsilon_{ij}$$ If the parameters of this model are estimated using frequentist method, a complex ...
