Is there any interest in supporting covariance matrices between different spectral elements? In `sncosmo`, we're looking at how we can fit models of supernovae to spectral data, and are interested in …

Hello! We are processing a dataset with hidden state numerical values and additional features like distance and velocity. When we run the dataset with just the numerical values, the model works but wh…

VAST::Summarize_Covariance has moved to FishStatsUtils::summarize_covariance, but that function still calls VAST:::calc_cov, which is not longer there.
Think its a simple change to FishStatsUtils…

While working with the ppx, I noticed something ... strange.
``` ocaml
# let x = Html5.Xml.W.nil () ;;
val x : '_a list = []
# let x : _ list = Html5.Xml.W.nil () ;;
val x : 'a list = []
```

Pyfixest currently has `predict()` function but there is not currently functionality to provide estimates of the variance of the predictions. (Some) other tools do include this, such as:
- Statsmo…

I ran 50000 steps with the Planck-2018 TT data firstly without a covariance matrix and got an abysmal acceptance rate of ~0.01.
During this run, it often gave this message ("failed to calculate covar…

## Current variance behaviour
Currently, definitions of interface implementations (i.e. `owns` and `plays` statements) are **covariant** in the implementing type (the owner or roleplayer), and **in…

there is a ValueError when I try to run the plot_em.py example. I use python 3.7 with numpy version 1.20.3 and scipy 1.6.3.

In your ml.py file, line 67 you have the following:
# Creating covariance matrix and training data on PCA.
cov_matrix = X_train.loc[:,X_train.columns != 'DJIA'].cov()
pca = PCA()
pca.fit(cov_mat…

**Summary**
'mmrm' already supports 'spatial' covariance structures. These are essentially covariance functions and allow fitting Gaussian process models.
GP models are particularly useful whe…
