How do you compare regression lines statistically? Imagine you are studying the relationship between height and weight and want to determine whether this relationship differs between basketball players and non-basketball players.

If you plug "statistics interview questions" into a search engine, you're going to get hundreds of questions and answers. And if your interview is looming in a few days, trudging through (and trying to memorize) hundreds of questions probably isn't your idea of a fun weekend. And if you're looking for that shoe in, having the perfect answer to every question might not be your best plan of attack. Why? Because that's what everyone else is doing.
So how do you stand out…Continue

While I was laid off due to the new Coronavirus, I created a computer application called Little Blue Pearl (LBP) - named after our planet. Although I was recalled about 1.5 weeks later, I find myself continuing to follow the fatality numbers for different countries. I guess it is a bit like bird watching in a certain sense. It is not that I am…Continue

Trying to gain organizational alignment on the best path forward on a critical product or organizational decision is overly difficult. Product-centric, inside-out organizations use “wear them down” decision-making techniques that leads to the “Least Worst” option because that option offends the fewest stakeholders.
This “lowest common denominator” approach leads to sub-optimal decisions from the perspective of what’s important to the customers. That’s like having…Continue

It is hard to underestimate the role of E-commerce in a world where most communications happen on the web and our virtual environment is full of advertisements with attractive products and services to buy. Meanwhile, it is obvious that many criminals are trying to take advantage of it, using scams and malware to compromise users’…Continue

Summary: High stakes models like those that allocate scarce resources to competing hospitals are headline news. New thinking contrasting model-based versus model-free learning are emerging to describe new conditions we must consider before building or evaluating those models.

This is a longer form followup to my post describing the open source pandemic package on PyPI (with Python code also available on Github). You can use the code to simulate millions of people moving about in two dimensions, crossing paths and, unfortunately, getting sick.
This video illustrates the dynamic with a toy sized town of fifty people. Watch how transmission takes place. You might even discern commuting and households.…Continue

The world is on the constant lookout for technologies that can help us further improve how we go about not only our daily lives but how we conduct business as well. And this search has led us to highly valuable resources: Geolocation and big data. We know the world is brimming with data, which makes it vital to use technologies that can help us sort through this data and make some sense of it. That’s where big data comes in — allowing us to extract value from the abundance of data. It is…Continue

In 1927, W. O. Kermack y A. G. McKendrick described the first mathematical model for infectious diseases using a set of differential equations. This model is called SIR because of the three states one individual can have.
These states are:

Multicollinearity occurs when independent variables in a regression model are correlated. This correlation is a problem because independent variables should be independent. If the degree of correlation between variables is high enough, it can cause problems when you fit the model and interpret the results.…Continue

About 4 months ago, I wrote for this blog an article entitled "List of Quantum Clouds". In that article, I listed 17 "quantum clouds". By now, there are probably a few more. The "HWB" (hardware backed) quantum clouds of Dwave, Rigetti and IBM, offer access to already existing, on-line qc hardware. I'll call all the other quantum clouds "proxy" quantum…Continue
