    Items discussed at the meeting:

    1. Bayesian statistics to optimize experiments i.e. when do I have good statistics to stop measuring?
    2. How to treat variables correlations
    3. Resolution functions for small angle scattering
    4. Bayesian model comparison (how to select good model for fitting)
    5. Bayesian statistics as way to avoid overfitting
    6. Bayesian statistics and...
