#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!

Matriz de scatter plots (ggpairs) 3x3 comparando tres medidas corporales para 3 especies de pingüinos de Palmer: Longitud Pico (mm), Longitud Aleta (mm) y Masa Corporal (g). La diagonal muestra gráficos de densidad para cada variable, coloreados por especie (Adelie, Chinstrap, Gentoo). Los paneles del triángulo inferior muestran scatter plots para cada par de variables, con puntos coloreados por especie. Los paneles del triángulo superior muestran el coeficiente de correlación de Pearson para cada par de variables, calculado para cada especie. El gráfico usa un tema con fondo beige y colores naturales para las especies. Fuente: paquete R palmerpenguins.

I have asked students in my #machinelearning and statistical modelling course to present 5 (self-selected) application papers demonstrating the use of experimental chemistry data for #multivariate models. The focus of the short presentation was on model quality parameters. 3 / 5 papers did not have any. Hopefully, this was not a representative sample. But there is work to be done! #academia #statistics #teaching #highered

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!
