GLSdetrended
GLSdetrended is a statistical method used to analyze time series data, particularly in the context of financial markets and econometrics. It is an extension of the Generalized Least Squares (GLS) method, which is a generalization of Ordinary Least Squares (OLS) that allows for the covariance structure of the errors to be non-diagonal.
The primary goal of GLSdetrended is to account for the presence of deterministic trends in the data.
The method involves two main steps:
1. Detrending: The deterministic components of the time series are removed. This can be done using various
2. GLS estimation: Once the data is detrended, the GLS method is applied to estimate the parameters
GLSdetrended is particularly useful in situations where the data exhibits both deterministic trends and stochastic components.
