The value of 'Point in Time' Talent Data

It's interesting when I read dismissive blogs about 'Point in Time' data suggesting it's no longer relevant. I would like to introduce one fundamental data type that does not change and directly impacts business performance: talent analytics. These are numbers representing stable characteristics about how we work naturally and what we are driven by. Think of them as your strengths in numbers form.

Since we all have people in our lives, I don't need to post 10 links…

'Point in Time' versus 'Through the Cycle'

Point in Time (PiT) v Through the Cycle (TTC)

There used to be an argument about this; its clear to me now that this is more than an arithmetic conundrum about Ratings and RWAs its a philosophical matter applicable to wider aspects of life & thus any arguments for PiT are just lazy and myopic. Here are some good recent references; I have selected recent papers since the debate has evolved towards a conclusion since it first developed 2 or so years ago. The game has…

A great statistical model for weather forecasts

For places such as the Pacific Northwest, UK or Germany, where weather is highly volatile, I believe that my mentor's model (when I did my PhD) might actually be the best one. In places where weather is easy to predict by looking at satellite images, you might be able to do well without any model.

The model described below is based on data from the Puget Sound (Seattle) area. For many years, weather forecasts for the Seattle area have been notoriously erroneous.…

A bank offering more than 60% interest rate on saving accounts

You read correctly, not 0.6%, not 6%, but 60%. This is yearly interest, and it requires some fair amount of work, but if you have between $10,000 and $100,000 in savings and can't find a job, this could be worth the effort. Indeed if you have $100,000 in savings you might just be able to survive thanks to the interest paid to you. The way it works is by leveraging new saving account products that banks offer. The more long-term deposits a bank receive, the more leverage it gets, the more…

Innovating Performance Models: Start with the Data You Own First

The recent "bigdata" phenomenon has introduced lots of trendy external data types like unstructured social media data. While this data is extremely valuable, IIA Faculty Member Greta Roberts makes the case that performance models should always include a fundamental, obvious, and readily accessible data…

Extract meta concepts through co-occurrences analysis and graph theory

....
So what I did is the following (be aware that is not the formal implementation of LSA!):
  1. Filter and take the base form of the words as usual.
  2. Build the multidimensional sparse matrix of the co-occurrences;
  3. I calculated for each instance the frequency to find it in the corpus;
  4. I calculated for each instance the frequency to find it in the doc;
  5. I weighted such TF-IDF considering also the distance among the…

Using Analytics to Connect Talent Characteristics with Enterprise Performance

Economic pressure drives businesses to find every advantage for increased business performance. While enterprises have carefully chosen key performance indicators, they are housed separately from key performance indicators of the people who do the work, missing an opportunity to quantitatively link a company's talent characteristics to business operations and outcomes.

IIA's January Office Hours call will discuss the connections between innate talent characteristics and enterprise…

Social media to determine the next President of United States: Flawed Poll, Intrinsic Bias in Social Media

See below Attensity's poll. Using Yahoo users, and Yahoo users only, as participants in the survey will result in a significant bias. This is bad from a design of experiments point of view, and no statistician would run a poll this way. Yahoo users (and social media users in general) are more liberal than other people. For instance, many older people or very poor immigrants who have no Internet account are quite conservative. This reminds me the famous poll 80 years ago when everybody…

Latest Article: Data Mining Lessons from the Movie "Moneyball"

My company (Discovery Corps, Inc.)  president Tim Graettinger has released a new article I think you'll like:

"If you’re a data miner, there’s a good chance you saw the movie Moneyball.  For me, the movie was entertaining, but the book was really enlightening.  I found it to be a source of numerous and familiar lessons about data mining - while couched in the intriguing context of major league baseball.  In this article, I’d like to share some of…

Business Technology: So, What's Your Algorithm? | Wall Street Journal

We are ruined by our own biases. When making decisions, we see what we want, ignore probabilities, and minimize risks that uproot our hopes.

What's worse, "we are often confident even when we are wrong," writes Daniel Kahneman, in his masterful new book on psychology and economics called "Thinking, Fast and Slow."

An objective…

A proposed new calendar could save more than 100 billions of dollars each year | MSNBC

Forget leap years, months with 28 days and your birthday falling on a different day of the week each year. Researchers at Johns Hopkins University in Maryland say they have a better way to mark time: a new calendar in which every year is identical to the one before.

Their proposed calendar overhaul — largely unprecedented in the 430 years since Pope Gregory XIII instituted the Gregorian calendar we still use today — would divvy out months and…

New highway toll system poorly designed due to lack of analytic thinking

As of yesterday, a toll system is in place for drivers crossing the I-520 bridge, linking Seattle to Redmond, where the big Microsoft campus is located. It is claimed to be the most modern toll system in US, and drivers don't need to stop to cross the bridge, there's actually no toll booths, no human beings to process your payment.…
