I ran a homemade study this morning to test the notion of "streakiness" in regards to Raul Ibanez.    Using Baseball Reference game logs, I condensed his stats into analysis block and tested to see if there was a correlation in OPS from one block of games to the next block.   Each analysis unit includes k games started;   the stats from the games in which he came on a sub are included however (basically, for each non-started game I carried over his hitting statistics to the next game).   I ran the study for k = 3,5,7,10, and 15.
