Our 40,000+Thoroughbred Databases and Software for Performance Prediction of Unraced Prospects

What data does EQB's DATAJOCKEY™ collect?

For the past 30 years, EQB has taken several measurements from Thoroughbred racehorses' cardiovascular systems using specialized equipment for two-dimensional ultrasound echocardiography. We have also digitized data from slow-motion films of thousands of horses. The resulting database, representing over 50,000 young, unraced horses at select quality auctions and farms, is carefully maintained and includes detailed race records (including date of race, racetrack, race surface, race number, distance, race level, time splits, finish position and earnings). Pedigree, conformation, veterinary exam notes and auction information are also stored with each record.

How should one use these several variables all together at once? How does one rank the relative importance of the different variables?

In the past, due to the lack of biostatistical mathematical sophistication in most veterinary school curricula, and to the large computer power required to process big, multi-variable databases into complex polynomials, studies usually tried to create simple ratios of pairs of variables and mathematically fit curves to them for two-dimensional graphs and equations. That is, they compared only two variables at a time for rankings of variables' relative importance to one another.

But with today's computers, a much better way is readily available, and it's called multivariate discriminant regression analysis. For EQB, this has allowed as high as a 48-axes “space” and higher order polynomial functions in describing statistically significant relationships and the reliability and reproducibility of their calculated probabilities in predicting subsequent racing performance.

Interestingly enough, even with these kinds of sophisticated statistical techniques, the relationships to subsequent performance of many traditionally used criteria for horse selection are still weak. Which is part of why it's so hard to find an elite racehorse. That's why EQB also uses non-traditional variables. And that's why traditional horsemen, even those in the Hall of Fame, rarely have over 10% of what they buy race at the highest levels.

By utilizing EQB's exclusive DATAJOCKEY™ service, clients take advantage of our massive, unique databases and the models developed from them, to assess a horse’s performance probability — even before they ever have a single race!

So how does EQB use multivariate discriminant analysis to contribute to the racehorse selection process? Just as most people can't visualize more than a three-dimensional space, they similarly can't conceptualize how more than three or four variables work together to form patterns. However, statistical programs can identify patterns in as many dimensions as there are variables to make up a pattern.

These are the same analytical procedures used routinely for human disease, medical device and drug studies.

An example of such a statistical procedure is the multivariate discriminant analysis EQB uses to predict horses' future racing performance based on cardiac measurements.

Multivariate discriminant regression analysis is especially useful for categorizing things into groups, such as high earners vs. low earners, or sprinters vs. routers. In medicine, similar programs are used to determine a patient's chances for survival with surgery after taking into consideration dozens of test measurements (there the groups, or “categories”, are, for example: live or die, or perhaps, if there are 4 categories: die, live one year, live 2 years, live 3 years+). When a doctor has 20 different test scores describing a patient's health, it becomes difficult to summarize what they all mean, since it's often not black and white. It's certainly difficult to condense all the different kinds of data available at racehorse auctions into clear purchasing decisions.

Can you visualize a 48-dimensional space (i.e., 48-axes graph)? Can you compare a dozen variables simultaneously? EQB's technology can.

EQB's exceptionally large and well maintained database, created over 25 years, allow it to be very precise in the creation of statistical models. For example, when EQB analyzes a 17-month-old horse's cardiovascular system, it compares that horse to hundreds of others (with detailed, known, subsequent racing histories) of the same sex, that were measured at the same age (within 30 days), and size (height and weight, e.g., within 25 pounds).

As an example of how EQB builds a computer model, it may take 1,000 high earners and give the computer all their vital statistics, such as sex, height, weight, age and several cardiac measurements (or data from biomechanical analysis of slow-motion videos of the way of going). Then it will create groups of terrible or modest performers. The computer then creates sophisticated statistical profiles to describe each group.

When an unraced horse's data is entered into the computer, the computer compares the new data with that of high and low earners it has already seen in its database. The computer assigns the new horse a probability of belonging to one group or the other. For example, it may calculate that a horse has a 30% probability of belonging to the high earner group and a 70% probability of belonging to the low earner group.

If you could visualize these statistics in a multi-dimensional space, the groups would look like planets (try to picture clusters of data points) in space. The models calculate the new horse's location (the location of its data point) between the clusters for the high and low earners. Complicating matters further, more than two groups can be compared simultaneously (such as low, medium and high earners), and the “space” can be (and in EQB's case is) composed of many more than three axes.

Multivariate discriminant analysis as a tool makes previous, simpler, statistical systems obsolete.

These same statistical techniques are routinely used in reporting studies on human drugs and medical devices.
