Que alegría carajo! Abajo los putos narcomunistas que tienen a este continente hermoso en jaque. Amigos venezolanos, los abrazo con aliento a champán. Venezuela es belleza y se merece la oportunidad de regresar al camino de esa libertad que el chavismo amordazó.

🌟👀 ¿Qué hacer cuando un resultado NO es estadísticamente significativo? 🧠
No te preocupes, no es el fin del mundo. 🌎
Aquí te dejo una guía para reflexionar y tomar el próximo paso como un profesional de los datos:
#stats#datascience#research#analytics#thesis#pvalue
Understanding the difference between t-tests and z-tests is essential for accurate statistical analysis. Both tests help compare means, but they differ in application based on sample size and population variance.
✔️ t-tests are ideal when the sample size is small or the population variance is unknown. They account for increased variability with smaller samples, providing a more accurate analysis.
✔️ z-tests are best suited for large sample sizes where the population variance is known. They are simpler and faster, making them practical when conditions are met.
❌ Incorrect test selection can lead to misleading conclusions, especially if the sample size is small or if assumptions about population variance are incorrect.
❌ Overlooking assumptions can result in inaccurate p-values and confidence intervals, undermining the validity of your results.
🔹 In R: Use the t.test() function for t-tests and z.test() from the BSDA package for z-tests.
🔹 In Python: Utilize scipy.stats.ttest_ind() for t-tests and ztest() from the statsmodels package for z-tests.
The visualization compares t- and z-distributions, showing how the t-distribution with degrees of freedom equal to 10 is broader, reflecting the higher variability typical of smaller sample sizes.

📢 ¡Estación R ya tiene web!
Hoy damos un paso importante en nuestra misión de impulsar el aprendizaje y uso estratégico de los datos: lanzamos la nueva web de Estación R.
Este sitio es el punto de encuentro para quienes buscan formarse, encontrar recursos y potenciar su trabajo con datos, ya sea desde el aprendizaje o la consultoría especializada. Allí vas a encontrar las secciones:
✔️ Cursos
✔️ Casos de impacto
✔️ Blog con herramientas
✔️ Servicios para organizaciones
🧠 Y esto es solo el comienzo: mañana abrimos inscripciones a "Dominando R, Potenciá tu Código" el nuevo curso para quienes quieren llevar su análisis de datos al próximo nivel.

Me metí a lo profundo de la Amazonía venezolana para ver las condiciones de la red de monitoreo atmosférico. Tomé fotos y hablé con fuentes locales e institucionales.
Les muestro el resultado de ese trabajo en un reportaje para @elestimulo. Pasen a leer:

A BIG STUDY in Nature Medicine:
Which food makes you age faster?
Scientists looked at 105,000 people in 30 years.
The statistics is impressive.
The study is open-access, so everyone can read it.
📍 Findings:
The diet that ROCKS: fruits, vegetables, whole grains, unsaturated fats, nuts, legumes, and some dairy products.
Adherence to this diet gives (on average):
- 86% higher odds of healthy aging at 70 years
- 224% greater odds for 75 years.
This was independent of other lifestyle factors, including physical activity level, smoking and BMI!
Basically, the diet should be LOWER in trans fats, sodium, and red and processed meats.
📍 Interesting points to note:
1. Olive / vegetable oil is best.
NOT Peanut oil. NOT processed Canola oil.
Look for extra virgin oil. It has less trans fat.
2. Wine is on the positive list. This is interesting, given all the controversy over its consumption.
3. Eggs make aging worse. I don’t know why.
One guess - maybe it’s due to BCAA (branched chain amino acids) that are assumed to accelerate aging? BCAA concentration in eggs is smaller than in salmon, chicken, or cheese. Yet, fish is better than eggs, but eggs are better than poultry. This is interesting.
4. Red meats are the worst. It’s even worse than sweets and desserts.
❗My point is simple:
Thinking of buying donuts? Skip it.
Thinking of going to McDonald's? Skip it.
Adding fries to your order? Go for a salad instead.
BUT for most people it’s hard.
Why? Because of survival instincts.
Our brain rewards sugar & fat with dopamine.
This is why we fancy junk food when we’re tired.
This is why big industry makes cheap unhealthy food.
This is why it’s so hard to break the addiction.
1. “Rewire” your brain by slowly changing habits. It takes time & money (healthy food is more expensive). DO invest into it. Break this dopamine loop.
2. Reduce your stress as much as possible. It plays a big role in unhealthy eating habits. There are many resources & podcasts that explain how to do it.
Age should be a number.
Not a disease.
Los países de América Latina están obligados a tomar partido ante la brutal dictadura de @NicolasMaduro quien está en el poder tras 3 fraudes electorales. No puede haber neutralidad ante los asesinatos, los prisioneros políticos y las torturas. El viernes veremos quién está con quién.
Aquí esperando a ver qué va a decir @fernandeznorona de su buen amigo @NicolasMaduro será que lo va a acompañar a la toma de protesta de su falsa reelección (?). Fraude cuando es para Morena, pero aplauden y solapan fraudes en otros países. ¿Autodeteminacion cuando le conviene?
@HSBC_MX el peor servicio del mundo! Un persona en ventanilla y una en atención al cliente. El único banco en Chetumal. Atención pésima para las personas mayores y embarazadas. En definitiva @HSBC_MX no es buena opción. Es la tercera vez que trato de hacer un trámite
🚨 ¡El R² no es lo que parece! 🚨 A menudo me preguntan cuál debe ser el valor deseable del R² o a partir de qué cifra podemos decir que nuestro modelo es adecuado. Pero esto no es tan sencillo como parece.🤯

June 21st is #ShowYourStripes Day.
It is an annual event where individuals, meteorologists, & organizations promote discussion about global warming by using @ed_hawkins iconic warming stripes.
Here is my animation showing local stripes around the world.
