In general, you're right that poor starters have bigger jumps once off the mark. Taking all batsmen (excluding a couple with poorly-behaved hazard functions) who average 35 or more, a regression on µ(1) - µ(0) against µ(0) gives <BR/>µ(1) - µ(0) = -0,73*µ(0) + 31,4. R-squared of 0,38. So those who start poorly jump up more once off the mark. Now there's a bit of a selection effect here - they all have pretty good (or better) averages, so they have to start getting better at some point. But it seems that much of that improvement comes once off the mark.<BR/><BR/>Now for some fast scorers. (I don't have strike rate data, so I'm just picking players here.)<BR/><BR/>player: µ(0); µ(1); µ(10); µ(30)<BR/><BR/>Sehwag: 9,0; 44,2; 44,2; 44,2<BR/>Gilchrist: 8,6; 26,4; 45,5; 60,8<BR/>Pietersen: 22,2; 44,7; 44,7; 44,7<BR/>Jayasuriya: 11,5; 38,4; 39,4; 39,9<BR/>McCabe: 14,5; 37,8; 45,5; 49,9<BR/>Lara: 12,5; 31,1; 47,0; 57,7<BR/>Hayden: 14,2; 49,9; 49,9; 49,9<BR/><BR/>The jump from 0 to 1 is looking bigger than average, overall. But I'm wary of generalising from a small sample, since when I did that before (with the suggestions in this post), they turned out to be mostly wrong once I looked at all players.David Barryhttps://www.blogger.com/profile/08378763233797445502noreply@blogger.comtag:blogger.com,1999:blog-22713811.post-21743463293667497222008-04-21T10:18:00.000+02:002008-04-21T10:18:00.000+02:00If you are interested in automation, perhaps you m...If you are interested in automation, perhaps you might try investing in MATLAB (http://www.mathworks.com). It's powerful and easy to use (for me anyway) and it can import excel files so no worries there.<BR/><BR/>I'd like to see how your hazard function deals with the 'poor starters'. People like S Waugh and Ponting (I am Australian, if you can't tell). And maybe you could compare them to the 'blazers', ie. Gilchrist, V Richards, Sehwag &etc. My theory is they will both jump significantly after the first run (like Sobers does).Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-22713811.post-9695751147096382602008-04-12T17:17:00.000+02:002008-04-12T17:17:00.000+02:00I think captains do tend to attack new batsmen tho...I think captains do tend to attack new batsmen though - there's almost always an extra couple of slips in for the new batsmen. And more attacking fields make it easier for the batsman to score runs, so it's a trade-off.David Barryhttps://www.blogger.com/profile/08378763233797445502noreply@blogger.comtag:blogger.com,1999:blog-22713811.post-66215847620813509342008-04-12T14:33:00.000+02:002008-04-12T14:33:00.000+02:00Begs the question why captains don't attack new ba...Begs the question why captains don't attack new batsmen more and never give them a cheap single.Anonymousnoreply@blogger.com
