#ncv — Public Fediverse posts

Question for the #stats folks working with #mgcv and #gam / #bam:
I'm dealing with a dataset with a high temporal autocorrelation, so after a lengthy discussion with the author of `gratia` (my current PI), we concluded that I should move away from AR(1) models and rather work with #NCV.
No problems with the setup, but the run time is forever.
My first model has been running for 20h by now, with no indication of how long it will take.
I have already switched over to #OpenBLAS, but it seems weird that my CPU load is constantly at only 15-25%. The only indication that something is happening is that RAM usage is slowly but steadily increasing.
I'm dealing with ~40k data points across ~300 time series, and a NCV window of 7 data points, so nothing crazy. The model includes two- and three-way interactions, and random smooths, but all of those things are biologically relevant.

I'd happily take any suggestions on how to speed things up, how to get proper CPU usage, or at least get an estimate of how far along the calculations are.

I might eventually need to switch over to #twlss, from the current `tw()`, and that will make things worse as that is not supported by `bam()`.

I'm currently on Windows, but I might be able to run things on an #HPC if needed, but not sure if I can easily fiddle with #BLAS there.

Pour un #maker ils font partie de l’équipement « de base ». On peut trouver des modèles de « très simple » à « très sophistiqué » (et très cher) mais le multimètre et la pince à dénuder sont incontournables. J’ai trouvé ce matériel chez #Tesmen : un multimètre automatique avec #NCV et une pince à dénuder avec détection de tension alternative #NCV intégrée

De Vegatariersbond biedt vandaag een petitie aan in de #TK dat in #ziekenhuizen zonder problemen een #vegatarische maaltijd beschikbaar moet zijn. Prima. Maar laten we er eerst voor zorgen dat er een gezonde #glutenvrije maaltijd komt. Vegetarisch is een keuze #coeliakie een ziekte. #ncv
