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 …

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 = []
```

# 🐛 Bug
Calls to _diagnonal() error when keops kernels are used. This showed up when tring to use keops kernels in a Multitask/Multi-output approximate GP with SVI. But below is a MWE of the failur…

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…

I would like to be able to run a GEE analysis using an unstructured covariance. In R this is very easy to do, e.g:
```
library(geepack)
geeglm(
outcome ~ . -cluster_id,
id = cluster_id,

Just wanted to park your gist here since I came across it this week, looking for similar. I don't know if it's something we want to include or if it belongs in scipy or scikit-learn (I don't think it'…

## 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…

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…

I know variance a big and confusing topic, but since we allow covariance for structures (e.g. passing `Array` as `Iterable`), maybe we could also allow it for abstracts (to pass `Array` to `ReadOnlyAr…
