Data set

Horse Racing Training set
  1. The first 10 months horse running results are posted as the trainig set.
  2. The file "training.zip" includes all 10 months.
  3. The description of columns is in the file "columns.meta".The columns are comma separated.
  4. Racing results of November and December will be used to test the model you build and will be posted after the deadline of the project.
Correction
The Wt column should be the weight the horse is carrying. You can ignore the parentheses after the numbers
Weight
The weight that the horse is carrying in stones and pounds. So, 10-04 means that the weight that the horse has to carry is ten stone and four pounds. This weight figure includes overweight, penalties and allowances.
For those not used to the imperial weights and measures there are fourteen pounds to one stone. There are roughly 2.2 pounds to a kilogram.
The horse's weight is connected to the horse's saddle cloth number. The horse with the highest weight (i.e. the one carrying the most weight) is the one with the lowest number.
The weight as displayed in the summary ratings is the total that the horse is to carry. Any exceptions for apprentices and/or penalties for recent wins are already included in the displayed value.
The time to look a horse's weight is to compare with its previous run and class. Could the rise/fall and weight help the horse this time? Some people have stated on the forum that laying a horse with the lowest weight is not a good idea and should be avoided.
