Curso de introducción a la estadística moderna con el entorno R

Comparto con ustedes la invitación que me llegó hoy:
Hola, ¿qué tal?

Te escribo para invitarte a tomar parte del curso "Estadística básica con R". Es una continuación del curso de introducción a R al que te apuntaste en primavera.

En aquel curso el objetivo era aprender a manejar R pero sin apenas discutir temas propiamente estadísticos. En esta ocasión vamos a introducir los conceptos más básicos de la estadística desde una perspectiva novedosa, basada en simulaciones y remuestreos, para los que R resulta una herramienta fundamental.

El curso no va a cubrir muchas técnicas concretas. Su objetivo es fundamentalmente replantear y repensar esos conceptos que subyacen a prácticamente todas desde una perspectiva computacional (de ahí el uso de R).

Los detalles del curso pueden consultarse en los dos enlaces siguientes

y sus respectivos enlaces.

Sería un placer poder volver a contar contigo en nuestro nuevo curso. Agradeceríamos también que nos ayudases a publicitarlo.

Un saludo de parte de los organizadores, Juanjo Gibaja y yo.
 Espero que muchos de ustedes aprovechen el curso :)

I won the Bad Graph Contest.

Last month Naomi Robbins featured her contest "Bad Graph Contest: What Software Produces the Worst Graph?". Yesterday I realized I won here:
Thank you to the organizer for the contest. It was very illustrative.
PD. I'm already thinking what to do with the prize :)

Immune retune: Recharging your body's natural defences

An extract of NewScientist:

"ACHOO!" A sniffling friend is sneezing just inches away. You would love to cover your face or run away, but in the interests of politeness all you can do is try not to inhale in their direction and hope your immune system is on the case.

Some people seem to catch everything that is doing the rounds, from coughs and colds to stomach bugs. Other people never seem to get ill. What's their secret?

A lot is down to dumb luck. There are some things affecting the performance of your immune system that you cannot change: your age, your gender, your genes, and most importantly, whether or not you have had a previous brush with an invading bug.

But there are plenty of factors you can control. I'm not talking about downing supplements sold as "immune boosters"; the claims for most such pills are not based on hard evidence. But there are plenty of other ways you can keep your immune system revved up and raring to go.

It's not all about boosting activity, though. Many common conditions are caused by the immune system reacting to things it shouldn't. When it attacks parts of the body the result is autoimmune disorders like multiple sclerosis, type 1 diabetes and inflammatory bowel disease. When it responds to molecules that are foreign but harmless, like those from pollen or peanuts, the result is asthma, eczema or allergies. Again, there are ways of encouraging your immune system to behave. So help it out by following these tips.

Eat yourself strong

Whatever the truth about chicken soup or superfoods, there are dietary interventions that appear to work

Befriend your bacteria

The human gut is riddled with bacteria that are essential for a healthy immune system – here's how to keep them happy

Don't stress out

Close your eyes. Count to 10. Whatever you do, stay calm. Stress can weaken the immune system transiently but significantly


Even a moderate lack of sleep can put you at greater risk of catching a bug – and don't think you can just get used to noise

Good day, sunshine

Autoimmune disorders like type 1 diabetes, multiple sclerosis and rheumatoid arthritis have been linked to a lack of vitamin D – the sunshine vitamin

Get bug-fighting fit

It can be hard to motivate yourself to exercise, but think of this: even short bursts of exercise give your immune system a temporary boost

Never too young

Breast milk, vaccines and playing in the mud is our prescription for child health

Age shall not wither you

The immune system declines with age, but there are things you can do to pep it up again – and new treatments could be on the way
