**Abstract**
We are working on implementing a Jacobian preconditioning method to accelerate chemical kinetics for large mechanisms in Cantera. The specific technique is referred to as adaptive prec…

I would like to see time-dependent covariates added for survival data. I have many clinical research studies that could use this.
The key idea that makes this possible is that for a Cox model, th…

Currently, gradients through lstsq are quite brittle because there is no custom derivative attached - this is described in the code since it was first implemented by @jakevdp here: https://github.com/…

Hi all,
I have a very odd problem with CLASS. I want to compute the density Cl with redshift space distortions (so I write in the parameter file "number count contributions" = density, rsd).
I als…

I wonder if your code is the whole PhD thesis or just chapter 6.
First of all, thanks for writing a program that solves the problem of local stability.I'm working on the boundary layer stability…

I'm not sure the exact problem, but it seems that the `mean()` of transformed distributions is not always correct. Here's an example of `exp()` applied to `dist_normal()`, which should yield a lognorm…
