#30DayChartChallenge Día 27: ¡Ruido! Analizando los residuos (el "ruido" inexplicable) del modelo CAPM para Telefónica (TEF.MC) vs IBEX 35. #UncertaintiesWeek #Finance

Este gráfico muestra la serie temporal del error diario del modelo (~18 años). ¿Es solo ruido blanco o algo más? Para comprobarlo, ¡test de Dickey-Fuller Aumentado (ADF)!

Resultado ADF: p=0.01. ¡Rechazamos la raíz unitaria! Esto sugiere que los residuos son estacionarios, fluctúan alrededor de cero como un "ruido" bien comportado (aunque su volatilidad cambia). ¡Buena señal para el modelo! (R²≈0.66).

Visualizando el componente idiosincrático y su (falta de) tendencia.

Another #Quarto + #RStats + Observable combination for Day 27 of the #30DayChartChallenge

Two heatmaps to illustrate the prompt of "Noise" - unsorted heatmaps look like random noise, (sensibly) sorted heatmaps are more likely to reveal patterns!

Let's keep going...

#Day27 A 2024 drama too few people watched

Definitely Branding In Seongsu.

It has an intriguing plot, the from-enemies-to-lovers romance trope and complex characters.

It's just too short. I would have liked more episodes to better develop the characters background.

#mapfailbruarychallenge Day 27 - worst decorations !
It's almost the end of this challenge, and this will most certainly be the last mapfail I produce on this theme! I think that, after all this experimentation, I've almost reached a definitive version. Just a few decorations, and it'll be perfect!

I'd like to recommend #NotOthers (#남남 )

The focus is about mother-and-daughter relationship, stronger than the conflicts both leads may face.
There's a bit of romance and crime/mystery solving too.
Both lead actresses are great at impersonating a strong woman character.

My #Day29 population map for the #30DayMapChallenge. I'm reusing my #Day27 data from the National Agricultural Statistics Service. The bubble map shows the number of equines (i.e., horses, ponies, mules, burros, and donkeys) in the conterminous US from the 2017 Census.

For #30daymapchallenge #Day27's theme of "Dot", I made this map of the number of people living in each US Census tract and Canadian Census subdivision in the Salish Sea Bioregion. This map shows 2010 data for the US and 2011 data for Canada.

You can explore human population characteristics in the Salish Sea Bioregion in more detail through the Human Populations chapter of the Salish Sea Atlas: arcg.is/0WaK51.

A map of dots for #Day27 of the #30DayMapChallenge. I'm a horseperson and I didn't know if a dataset existed for a horse census (not wild) in the US. Luckily, I found one with the National Agricultural Statistics Service. https://www.nass.usda.gov/ The dot density map shows the number of equines (i.e., horses, ponies, mules, burros, and donkeys) in the conterminous US from the 2017 Census. One dot = 500 head.

Why, yes, she has changed. She’s a much hotter mess than she was when we started this journey together. I suppose that’s how #TimeTravel works.
