Does WAV Detrend and Normalize Data ?
You have the option to let WAV preprocess your time series data before WAV begins its smoothing and sampling stage. There are two types of preprocessing: DETREND and NORMALIZE. • DETREND — Use this option when your price data tends to wander in value over time. With DETREND you are feeding WAV time series data that is always centered around zero. This makes some modeling and forecasting tasks much easier. • NORMALIZE — Use this option when the volatility of your data tends to wander in value over time. With NORMALIZE you are feeding WAV time series data whose volatility (as measured by standard deviation) is relatively constant. This makes some modeling and forecasting tasks much easier.
