Fantasy Sports Betting: The Next 'Big Thing' Thanks to Big Data

Many believe that Fantasy Sports Betting (FSB) is the next immensely popular online game, similar to the arrival of Poker a decade ago, and the incredible growth of the industry in the USA is the best proof of that.

Since betting on sporting events has been increasingly evident since the turn of the century and has become a global professional sports sector in itself, it makes sense to explore how it can merge together with FSB. Are they complementary products or is…

  • Bokeh - Bokeh provides a bit more interaction than Seaborn, but it is still not fully interactive. 

For R: …

  • Affordability (1/3):the overall cost of the program and/or credit hour.
  • Flexibility (1/3): the number of credit hours and/or the length of time it takes to obtain the degree

9 Must-Have Skills You Need to Become a Data Scientist

Usually I tend to criticize this type of articles, but in this case I agree pretty much agree with BurtchWorks, the author of this article, even though the article is more than 6 months old. Note that BurtchWorks is a recruiting firm that recently posted interesting salary surveys for data…

Types Of Performance Metrics Everyone Must Differentiate

There are leading and lagging indicators in business. It is important that managers understand the difference between them and ensure they have both types of metrics to get an accurate picture of performance. However, there are also some important issues to watch out for.

All performance measures are, by definition, backward looking. They tell us what has already happened. Current trends are on merging the data and information from backward looking metrics or performance indicators…

Structural Relationships in Data

The first computer program that I encountered mimicking or emulating human interaction through language was called "Eliza." The version that I knew ran on the Commodore PET. It communicated in English. Eliza made comments that made some sense but which indicated lack of understanding of the conversation. If a person mentions "mother," Eliza might…

Spectacular patterns found in rare, big numbers used in encryption schemes

This may lead to a practical, feasible solution, to factor the product of two very large prime numbers (with thousands of digits), making many security systems vulnerable to new types of attacks: factoring encryption keys, en masse.

Let's start with the pictures. The patterns (as well as how to leverage them) are explained below.…

A Database of Police Killings Since 2013 by Justin Tenuto

A while back, we found an interesting dataset online. The URL, killedbypolice.net, is fairly self-explanatory. It's a community-sourced list of all "police-involved fatalities", started in May of 2013, but the data itself was a bit jumbled and messy. Race and gender identifiers were in the same column, dates were inconsistent, and though most entries had a news story, we felt there was more information we wanted to know. We put the dataset…

After searching the net I have found certain references made only to the extent of creating the dash boards in terms of providing the visibility to the data, which is also a part of BI.

Big Data = 3 data issues

There are at least two definitions for Big Data: a broad sense definition and a strict sense definition. For the broad sense definition, Big Data includes all the possible available data on earth.  For the strict sense definition, Big Data is a term for large datasets that traditional data processing applications cannot handle. We are going to follow this last approach.

For Davenport [2014] “Big Data refers to data that is too big to fit in a single server, too unstructured to fit…
