Time series analysis with long memory
WebOct 15, 2024 · Naive Time Series Method. A naive forecast – or persistence forecast – is the simplest form of time series analysis where we take the value from the previous period as a reference: xt = xt+1 x t = x t + 1. It does not require large amounts of data – one data point for each previous period is sufficient. Additionally, naive time series ...
