#30DayChartChallenge Día 15: Complicated Relationships! 🐧↔️🐧

Hoy, una matriz de scatter plots con ggpairs para explorar las relaciones entre medidas corporales (Long. Pico, Long. Aleta, Masa Corporal) en los pingüinos de Palmer. ¡Perfecto para el prompt "Complicated"! #RelationshipsWeek #Animals

La matriz lo enseña todo:
* Diagonal: Distribución de cada medida (densidad).
* Abajo: Scatter plots de cada par de medidas (coloreado por Especie).
* Arriba: ¡La correlación $ entre ellas!

Se ven las fuertes relaciones positivas (más grande = aleta más larga) y cómo las especies (Adelie, Chinstrap, Gentoo) forman clusters distintos en este espacio de rasgos. ¡Una forma densa de ver muchas relaciones a la vez!

Anyone know of software that will help optimize multi-variate experiments? Something sample-efficient since these are manually generated test results.

I found https://github.com/yunshengtian/AutoOED/ which looks great, but having a hard time getting it working at the moment

Our article @MethodsEcolEvol on incorporating predictors in a model-based ordination is now out!

We develop a new implementation for constrained ordination in the #GLLVM R-package, but also develop a new kind of ordination.

Concurrent ordination combines the best of unconstrained and constrained ordination. It leaves the latent variables unconstrained but uses predictors to inform the ordination anyway!
