Bayesian Modeling and Probabilistic Programming in Python
### Issue with current documentation: [`pymc.sample`](https://www.pymc.io/projects/docs/en/v5.10.0/api/generated/pymc.sample.html#pymc-sample) was replaced by [`pymc.sampling.mcmc.sample`](https://www.pymc.io/projects/docs/en/latest/api/generated/pymc.sampling.mcmc.sample.html#pymc-sampling-mcmc-sample) in the documentation after `v.5.10.0`, but `pymc.sample` can still be called under `pymc-5.10.2`. ### Idea or request for content: _No...
## Description FutureWarning when users access sumto1 transform to let them know it's deprecated and will be removed in the future, and a test that verified the warning is working...
### Description Because we don't save transformed variables in the returned InferenceData (why not?) it's not easy to evaluate the model logp once we have a trace. ~~One could rewrite...
Squeezing stats by default removes the `"stepmethod"` dimension (which we don't name explicitly), but this does not always work [for `object`-dtyped stats](https://github.com/pymc-devs/pymc/blob/d47dac0e92da2398206b42d3748bc63ff7ff7103/pymc/backends/base.py#L210-L215). This is (very often) the case for the...
### Description Sometimes models with large Deterministics run out of RAM during sampling. One could compute the Deterministics afterwards easily, but would need to create the same model twice, once...
### Describe the issue: So I am trying to implement a MvNormal where the covariance itself is hierarchically dependent on other priors. I have also sort of described the issue...
### Describe the issue: I wanted to test the detection for several breaking points in a time series, so I came up with the following model (cf. code example) to...
### Describe the issue: In `pymc.sampling.jax.sample_numpyro_nuts`, a jitter is always applied to the initial values through function `_get_batched_jittered_initial_points()`: https://github.com/pymc-devs/pymc/blob/904a0eaac216732bc358dd91680cd428d95704f0/pymc/sampling/jax.py#L662-L668 This function actually accepts a `jitter` argument that allows jittering to...
This PR will add implementation of default rewrites for nodes with inner `fgraph` and related with issue #6697. For now I just added new test cases ---- :books: Documentation preview...
