“Home” isn’t what it used to be in the NBA…why?

It is well known that homecourt advantage is powerful in the NBA, and in basketball; however, over the past few decades, this effect has been changing…substantially.

What factors contribute to this advantage, and how can we statistically measure these factors? I have seen many analysts and individuals discuss the possible causation…but very few have sought to measure the different components.

To do this, we captured a decades worth of data from…every score from every game all the way back to the 1940s…back when the NBA was called the “BAA”.

There’s a bit of magic to homecourt advantage…let’s see if we can demystify it.
