How to avoid new bank fees: solution

Most banks are going to add small fees e.g. for debit card ($3/month in my case). Last time I went to my bank, I had this strange conversation:

  • I asked documents about the various types of accounts that they offer, as they suggested that I switch to a more upscale type of account, where there would be no fees
  • Instead of receiving the documents, I was forced to spend 15 minutes listening to a bank manager about the benefits of the upscale account. My hourly rate being…

New ways for publishers to monetize content: our solution

How we moved from cave-man publishing - traditional web site funded by job ads - to where we are now:

Misuse of statistics in court leads to wrongful conviction and death of Sally Clark

She conceived two sons in 1996 and 1997. Both died from infant death syndrome after one month. The statistical expert testifying in court said that the chance of such a rare event is one in 73 million. She was convicted of murder and imprisoned. Freed a few years later, her life was destroyed and later died of alcohol poisoning.

My rebuttal to the 1 in 73 million argument is as follows:

  • Even if "1 out of 73 million" was the correct probability, the fact that there are…

How do you become a data scientist?

I have read several articles on the subject, but none of the authors were really “Data Scientist” and they admit that, so I thought it was time that something was written by an actual Data Scientist.

First off, let’s make sure you understand that there’s lots of college involved, no way around that one. If you noticed a lady in the 2nd row, 3rd from the left had a mole on her nose in the last commercial you watched, you might have what it takes, even if you hadn’t thought of…

Online advertising: a solution to optimize ad relevancy

Bayes theorem challenged in court | The Guardian

Bayes' theorem.

A formula for justice

Bayes' theorem is a mathematical equation used in court cases to analyse statistical evidence. But a judge has ruled it can no longer be used. Will it result in more miscarriages of justice?

It's not often that the quiet world of mathematics is rocked by a murder case. But last summer saw a trial that sent academics into a tailspin, and has since swollen into a fevered clash between science and…

Home-made clinical trials lead to a cure for widespread skin complaints

One of my friends (referred to as the patient) holds a Ph.D. degree in statistics and has been affected with a common skin condition for more than 20 years, known as rosacea (http://www.ncbi.nlm.nih.gov/pubmedhealth/PMH0001882/). Here we report how he came with a solution to fully eliminate the problem. Physicians traditionally agree that there is no cure for rosacea.

Interesting note and questions on mathematical patents

I was reading about the "Automated Reduced Error Predictive Analytics" patent secured by Rice Analytics (see below) and my first question is:

How can you successfully sue competitors about using a mathematical technology? After all, most vendors offer error and variance reduction as well as dimension reduction and automated model selection (based on optimizing goodness-of-fit) in their software. All statistical and data mining consultants, including myself, also use similar…

Number of Americans with no job for a year or more

A chart that speaks by itself. Couldn't be described any better by using words. Of course, population grew between 1970 and 2010, but not by 400%. Did the definition of unemployed changed between 2007 and 2009?

The new superstars: data scientists | Silicon Angle

 

Data Scientists are the new rock stars of the technology world.

Don’t believe me? At last week’s Strata conference, throngs of attendees were jockeying so intensely for position to listen to bitly Data Scientist Hilary Mason that I thought I might be at a Bon Jovi concert circa 1986.

Ok, perhaps I’m exaggerating just a…
