I'm trying to estimate the accuracy of the judgment for each time using the state-space model. The R code is as follows. MacOS 10.14.6, rstan 2.21.2 w ...

I am having trouble when I want to set initial values for parameters in a Stan program for MCMC using cmdstanr. The relevant guidance in the documenta ...

This feels like a duplicate question, but I can't find it anywhere here or elsewhere! So, in R, you can comment out a block of code with Ctrl + Shift ...

I saw a Stan program where the data block contained int person[N_obs]. Is this creating an array of integers of size N_obs that is called with person? ...

I am interested in models where the observed data is a discretization of a continuous latent parameter. As a simple example imagine that you have obs ...

Suppose I want to declare a matrix mat with ncol columns, where ncol is a function of some data foo. I could accomplish this with the below data block ...

I'm on a Mac X1, Monterey. I've installed prophet and run into this issue when trying to fit a model. I know this has to do with the wrong paths b ...

I run simulations on a hpc-cluster which are quite memory demanding. I'm fitting cmdstan models with 3000 iterations for different conditions(200 uniq ...

The default install location for cmdstan is $HOME/.cmdstan. In a singularity container, I can install cmdstan somewhere else (e.g., /opt/cmdstan). T ...
