Wind,Temperature,Air Pressure statistics

The above graphs show statistics from SMHI, the swedish meteorological and hydrographical institute, on air pressure, temperature and wind speed.  For each categrory, (pressure,temp,wind speed) there are two graphs: the first a frequency chart, the second a Q-Q-chart, showing the … Continue reading

MH370 and Bayesian reasoning: example of SAR optimization

In two previous posts, [1,2] I’ve covered the fundamentals of Bayesian probability theory.  The second post looked into how the air distaster investigation team might have proceeded, once they received Inmarsat’s satellite data, to assess the likelihood of the flight path … Continue reading

Bayesian reasoning and SAR for flight MH370

I covered the basics of Bayesian reasoning in a previous post. So, let’s apply Bayesian reasoning to the search & rescue operation of flight MH370. As we now know, Inmarsat’s identification of the most likely path taken by MH370, by … Continue reading

Are you smarter than 80% of professional gynecologists…?

Several studies, e.g this one, show that most people, including professionals in domains where knowledge of chance and odds matter, have difficulties understanding probabilities. Take the following example (from the linked study above): – it is known that in a … Continue reading
