**Description of the issue**
This is meant to discuss how to properly compute the covariance matrix:
- is it correct to take into account the sky coverage correction, i.e. f_{sky}=12.25/5000 to …

I wonder if someone could clarify what P0 really is. For instance, in the example notebooks to pymc-experimental , I found the following statement:
P0_diag = pm.Gamma("P0_diag", alpha=2, beta=5, di…

[`celeri.py` currently uses pandas to read in a dataframe from a `.csv` file](https://github.com/brendanjmeade/celeri/blob/468c373c3d3443b2974e1e0ac04dd370df0ff882/celeri/celeri.py#L576) with the colu…

I would like to ask you about the derivation of the rotation matrix W with respect to the Lie algebra in "MonoGS". Why can it be derivated directly in this way? Why not derive W@Sigma (3D covariance)?…

There is no `PythonCovarianceModel` class in OpenTURNS. Hence, we cannot estimate the hyperparameters of a covariance model with maximum likelihood method that would be defined in Python. This prevent…

**update** basic models are merged, extensions missing, e.g. essentially only biweight norm has full support
Maronna and Yohai 2017 recommend MM-estimator for p < …

I encounters infinite loop when i run a saga_gui.py
First, the torch version caused the following error in def pca.

there are some confusing caculations of gradients, i try to understand it, maybe i need some help:
(1)If gradients is calculated according to 'cov2D = transpose(T) * transpose(Vrk) * T;' some T_ij se…

Hey QuantEcon folks!
I was going through the SVD lecture (lecture number 5) and came across the section on PCA (5.8). Having re-read the section a couple of times, I see that the description of the…
