It seems early Ottoman sultans abdicated and retired before they died at a higher rate than many other contemporary empires. Why was this?

Bayezid and Murad both did it, I'm sure others did as well. I remember it being a huge deal historically that Diocletian retired in Rome, so what's the situation in the Ottoman Empire? I've heard it suggested that this was to ensure a peaceful transition of power, but the Ottomans had peaceful transitions of power when sultans held on until their deaths, so I'm really not sure about this.
