- 1. Data Exploration Thoroughbred Horse Racing N RAMACHANDRAN
- 2. Transform Qualitative Variables to Quantitative • Transforming the qualitative variables which have a significant impact on the handle : 1.Race_Type:dummy_allowance , dummy_handicap , dummy_stakes , dummy_maiden , dummy_starters,dummy_claiming 2.Age Restriction:dummy_is2allowed , dummy_is3allowed, dummy_is4allowed, dummy_is5allowed, dummy_isg5allowed 3.Surface : dummy_dirt , dummy_turf 4.Track Id:dummy_AD ,dummy_CD , dummy_CRC, dummy_FG
- 3. Derived Variables • Hour of race : Getting the hour of race in 24hr format • Day of race : Getting the day of the week (1: Sunday , 7: Saturday) • Month of race :Gettting the month of the race(1:Jan , 12:Dec)
- 4. Summary Statistics • No missing values .Some of the data not available for conditions_of_races , sex_restriction are assumed to mean that there are no conditions or restrictions and hence the field is blank. • Proc means and proc freq data on the expected lines .Nothing unusual to be reported from the data.
- 5. Graphical Analysis • Compared different independent variables to the dependent variable handle and generated some charts.

- 9. Average Handle vs No of runners • The average handle increases from no of runners from 4 to 12 and the client is suggested to keep this range to maximize profits. 0 100000 200000 300000 400000 500000 600000 700000 800000 900000 1000000 3 4 5 6 7 8 9 10 11 12 13 14 HANDLE No of Runners

The client can be suggested to schedule the races as such.
- 11. Handle Value Graph • All the high values of the handle look like an outlier but the reason behind them is that they are mostly placed on the weekends (ie on holidays) 0 1000000 2000000 3000000 4000000 5000000 6000000 1 177 353 529 705 881 1057 1233 1409 1585 1761 1937 2113 2289 2465 2641 2817 2993 3169 3345 3521 3697 3873 4049 4225 4401 4577 4753 4929 5105 5281 5457 5633 5809 5985 6161 6337 6513 6689 6865 7041 7217 7393 7569 7745 7921 8097 8273 8449 8625 8801 8977 9153 9329 9505 9681 9857 10033 10209 10385 10561 handle
- 12. Handle vs Track Id • From data it can be inferred that the average handle at Churchill Downs in the state Kentucy is significantly greater than its peers. 0 100000 200000 300000 400000 500000 600000 700000 800000 900000 AP CD CRC FG Count of handle Average of handle2
- 13. Anomaly Detection • In the handle graph(11th slide) , there are some spikes in the values which turnout to be weekends when high transaction handle occurs , so could not be termed as an outlier. • There is only one day(26-Oct-04) where we have no of races =15 , so that can be an outlier .
- 14. Suggestions for client(Summary) • As described in the few graphs and histograms , some of the things the client should take into account are : • 1.Wed , Fri , Sat , Sun : are the highest gross handle days in a week. • 2.Steep increase in handle when the purse is higher than 150000$. • 3.Restrict the no of races to 11/day. • 4.Average handle increases when the no of runners are in 4-12 range. • 5.Value of the handle is significantly high if the first race is in 11-12pm and the last in 7-8pm range.
