Sarah Lee AI generated o4-mini 5 min read · April 19, 2025 Cointegration is a fundamental concept in modern econometrics, capturing stable, long‐run relationships among nonstationary time series. When two or more series share a common stochastic trend, standard regression techniques can produce spurious results1. The Johansen test (Johansen 1988; Johansen & Juselius 1990)2 addresses this by offering a likelihood‐based method to detect and estimate multiple cointegrating vectors in a Vector Autoregressive (VAR) framework. A kkk‐dimensional VAR(ppp) model can be written as: Δxt=Πxt−1+∑i=1p−1ΓiΔxt−i+ut, \Delta \mathbf{x}t = \Pi \mathbf{x}{t-1} + \sum_{i=1}^{p-1} \Gamma_i \Delta \mathbf{x}_{t-i} + \mathbf{u}_t, Δxt​=Πxt−1​+i=1∑p−1​Γi​Δxt−i​+ut​,

Johansen uses the eigenvalues of matrices derived from residual covariance estimates to test: Sarah Lee AI generated Llama-4-Maverick-17B-128E-Instruct-FP8 7 min read · May 28, 2025 The Johansen Test is a statistical test used to determine the presence of cointegration among multiple time series. Cointegration is a crucial concept in econometrics and finance, as it helps identify long-term relationships between variables. In this article, we will explore the Johansen Test, its significance, and its applications in data science. The Johansen Test is a multivariate test that examines the cointegration of multiple time series.

It was developed by Søren Johansen in 1988 [^1]. The test is used to identify the number of cointegrating relationships among a set of variables, which is essential in understanding the long-term dynamics of the variables. The Johansen Test is significant in data science because it helps in: The Johansen Test was first introduced by Søren Johansen in his 1988 paper, "Statistical Analysis of Cointegration Vectors" [^1]. The test was later refined and extended in subsequent papers [^2], [^3]. Today, the Johansen Test is widely used in econometrics and finance to analyze multivariate time series.
