Este tío simpático es Guy Goma. En 2013, acudió a la BBC a una entrevista (de trabajo, cabe precisar). Guy, entonces en paro, aspiraba a un puesto de técnico informático. La entrevista tuvo lugar, solo que de la manera más irreal posible. El resto es historia.

HILO.

About a year ago, we embarked on a quest to answer one of the most intriguing questions:

If you flip a fair coin and catch it in hand, what's the probability it lands on the same side it started?

Today, we are finally ready to share the results.

"Absence of evidence is not the evidence of absence"

Understanding Confidence Intervals

1/ Let’s start with a scenario: Imagine a doctor wants to estimate the average blood pressure of all adults. It's impractical to measure everyone, so she takes a sample of 100 adults and calculates the average blood pressure to be 120 mmHg.

2/ Now, the doctor knows that this is just an estimate, and if she took another sample, she might get a different average. So, how can she express the uncertainty around her estimate?

3/ Enter Confidence Intervals (CIs): A CI is a range of values, derived from the sample data, that is likely to contain the true value of an unknown population parameter.

4/ For example, the doctor might say she is 95% confident that the average blood pressure of all adults is between 115 and 125 mmHg. This is a 95% confidence interval.

5/ How to calculate it? For a 95% CI, you would use the sample mean (average) +/- 1.96 * (standard deviation / sqrt(sample size)). The 1.96 comes from the fact that 95% of the area under a normal distribution curve lies within 1.96 standard deviations of the mean.

6/ So, if our doctor's sample had a standard deviation of 10 mmHg, the 95% CI would be 120 +/- 1.96*(10/sqrt(100)) = 120 +/- 1.96, or 118.04 to 121.96 mmHg.

7/ Interpretation is key: Saying “I am 95% confident that the average blood pressure is between 118.04 and 121.96 mmHg” does NOT mean that there is a 95% chance that the true average falls in this range.

8/ Instead, it means that if you were to take many samples and compute a 95% confidence interval for each one, about 95% of these intervals would contain the true average blood pressure.

9/ It’s important to choose an appropriate confidence level. 95% is common, but in some cases, you might want a higher or lower level. For example, if the consequences of being wrong are very severe, you might choose a higher confidence level, like 99%.

10/ However, higher confidence levels result in wider intervals, and vice versa. So, there is always a trade-off between precision and confidence.

11/ Limitations: CIs assume that your data is normally distributed, which may not always be the case. Also, they can sometimes be misinterpreted or misused, so it’s important to understand them properly and communicate them clearly.

12/ In summary, confidence intervals are a useful tool for expressing the uncertainty around an estimate, but they have their limitations and should be interpreted and communicated carefully.

I used to teach game theory, both undergrad & phd levels. One game I would do at start is version of Keynesian beauty contest: everyone picks a number 0-100, person closest to 2/3 of average wins. Nash is 0. But anyone choosing 0 loses, bc the class aren't (yet) game theorists. >
