Hi UB,
I wanted to alert you to something unfortunately.
I have gone through the Betfair data, and it is completely wrong.
So unless you have your own data, ditch my idea, because the data was dirty.
This is only the tip of the iceberg from the errors I found:
a) non runners included
b) large chunks of races missing data
c) Winners missing
d) dead heats not accounted for, i.e. the price is the same for deadheats.
e) results and placings missing
All in all very disappointing, I cleaned it up as best I could, but the data was too far gone.
This is the data from their csv files.
