Shelia’s wheels within Shelia’s Wheels – Dan Davies
“The conclusion I take away is that once more, a simple bonus-malus system (the “no claims bonus”) is not easily defeated, and also that most of the time, big features of datasets are big features that are easy to recover from correlated characteristics. (This is what makes me a big sceptic about futurists talking about genetics in health insurance, telemetrics in motor or AI in everything – if something’s big enough to be relevant to pricing, it’s generally really big and easy to find)”
