  • Step-by-step example of Bayesian t-test?
    4 projects | /r/AskStatistics | 3 Apr 2022
    Okay so first off, I recommend that you read [this]( article about "The Bayesian New Statistics", which highlights estimation rather than hypothesis testing from a Bayesian perspective (see Fig. 1, second row, second column). Instead of a t-test, then, we can *estimate the difference* between two groups/variables. If you want to go deeper than JASP etc, I recommend that you use [brms](, or, if you want to go even deeper, [Stan]( (brms is a front-end to Stan).
  • [R] Are there methods for ridge and lasso regression that allow the introduction of weights to give more importance to some observations?
    2 projects | /r/MachineLearning | 23 Aug 2021
    I think the brms package ( or the blavaan package ( have support for SEM. I've never done it myself, so I unfortunately can't give you any direction for that in particular. However, I have used stan in multi-level meta-analysis regression (combining multiple CRISPRa experiments to find determinants of CRISPRa activity, see and had some success.
  • I have a small sample size time series with potentially lagged predictor values which are also time series. What could be potential methods to analyse these data?
    3 projects | /r/AskStatistics | 25 Apr 2021
    Anyway, I found I can include weights into the brm function by using gr(RE, by = var) to deal with the heterogeneous variance and it should automatically assume that each observation within a group is correlated according to the brms reference manual.
  • Brms: adding on a nonlinear component to working MLM model
    2 projects | /r/AskStatistics | 28 Feb 2021
    This is what actually should work- I must be declaring my variables incorrectly. The issue I'm having is that what you refer to as lin , I tried calling a few things, from b to LinPred (which worked in the link here: brms issue 47). When I've tried doing this, I receive errors that say "The following variables are missing from the dataset....[insert variable used to symbolize linear part of the model)". But I believe you're code is on the right path for what needs to be done- I'll try altering my syntax to be sure it resembles yours let you know if it works.

    Unfortunately, I can't just tag it onto to the working linear piece because brms doesn't allow for more than 2 level factor covariates in NL formulas. After much googling, I was able to find these brms github posts: 46 47 where they discuss how a NL component can be added. I've tried the syntax used, but it's still throwing errors. Here is one syntax I tried, going off of the information on those two links (where b1=lambda, b2= kappa)
