WebJan 2, 2024 · Using the change in gold price, build a Gaussian emission HMM using hmmlearn. We chose the Gaussian emission as it is the most straight forward model and the easiest to interpret. We assume that there are 3 different hidden states in the gold price data corresponding to low volatility, medium volatility and high volatility.
