A Note on Numerical Modality in Large Datasets

Numerical Modality

The mode is one of the basic statistics which is defined as the most common value over an array. When the values of the array are categorical, the mode is easy to detect by selecting the one with the most occurrence. The problem of identifying the modes on a numerical array is harder since the values…

How I Learned to Stop Worrying and Love Uncertainty

Humans and uncertainty

Given these troublesome times in terms of economy, and our endemic problems as a country, like drug traficking, corruption and violence, it will be a message worth observing and analyzing.

To this end, a few independent news outlets have taken upon themselves to embark on a live 'fact-checking' event.…

Why I don't like IT ppl in my Analytics team

In the beginning, there was Statistics, and for a time, it was good: it allowed Fisher to measure farm productivity. Then came Computer Science, and for a time, it was good: combined with Stats, it allowed the allies to save lives and fuel in WW2. Then came the IT barbarians, with their tool-centric religions, fads and next-coolest-framework cult. Analytics went downhill from there.

Sorry for the inflammatory intro, but despite the hyperbole, the fact remains: IT has not helped… Continue
