This issue aims to discuss the possible reasons why the theoretical angular power spectrum does not match the one computed from the log-normal simulated maps when we sample from correlated maps.
Aft…

I am simulating data according to a logshifted distribution in order to test my model before running it on real data.
As expected, the shifted lognormal family in brms only accepts positive values,…

I have a model with a predictor modeled shifted lognormal with measurement error that samples fine using `rstan`.
When I ask for `pp_check` or `bayes_R2` I get the following error that seems to com…

As noted in #3, @tbuehrens made a good suggestion about putting the density dependence in egg-to-smolt survival instead of spawner egg deposition. I had to work through the algebra to convince myself …

standard rate bounds for integration are 1bp - 200bp, this is adjusted by a shift for shifted lognormal volatility input; however when the volatility input is normal, the rate bounds remain unchanged …

I think it would be a neat addition to generate Discrete-value hyperparams. You could redefine Boolean (which should really be called Bernouilli in my opinion) to be Binomial(1,p).
In the mean time…

The following common "customized distributions" are missing / faulty / only implemented for unobserved variables. It would be nice to have a standard API for when all of these get implemented for both…

Hello,
I fitted 2 models, 1-2 years apart, using the `shifted_lognormal()` family argument (with default links). The earlier one is as below,

I have been working with lognormal distributions as a proposal distribution for some MCMC routines which require the proposal distribution to have some **pre-defined sample mean and variance**, `m` an…
