Finding the Beatle who wrote each song using statistical models

There’s been some disagreement about who wrote “In My Life” by The Beatles, so researchers did what any normal person does and tried to model the songs of Paul McCartney and John Lennon:

Mark Glickman, senior lecturer in statistics at Harvard University, and Jason Brown, Professor of Mathematics at Dalhousie University, created a computer model which broke down Lennon and McCartney songs into 149 different components to determine the musical fingerprints of each songwriter.

McCartney says he wrote the music for the song, but Glickman and Brown give that claim a less than 1 in 50 chance.
