Test for no-cointegration of a univariate equation. The null hypothesis is no cointegration. Variables in y0 and y1 are assumed to be integrated of order 1, I(1). This uses the augmented Engle-Granger two-step cointegration test. Constant or trend is included in 1st stage regression, i.e. in cointegrating equation.

Warning: The autolag default has changed compared to statsmodels 0.8. In 0.8 autolag was always None, no the keyword is used and defaults to “aic”. Use autolag=None to avoid the lag search. The first element in cointegrated system. Must be 1-d. statsmodels.tsa contains model classes and functions that are useful for time series analysis.

Basic models include univariate autoregressive models (AR), vector autoregressive models (VAR) and univariate autoregressive moving average models (ARMA). Non-linear models include Markov switching dynamic regression and autoregression. It also includes descriptive statistics for time series, for example autocorrelation, partial autocorrelation function and periodogram, as well as the corresponding theoretical properties of ARMA or related processes. It also includes methods to work with autoregressive and moving average lag-polynomials. Additionally, related statistical tests and some useful helper functions are available. Estimation is either done by exact or conditional Maximum Likelihood or conditional least-squares, either using Kalman Filter or direct filters.

Currently, functions and classes have to be imported from the corresponding module, but the main classes will be made available in the statsmodels.tsa namespace. The module structure is within statsmodels.tsa is stattools : empirical properties and tests, acf, pacf, granger-causality, adf unit root test, kpss test, bds test, ljung-box test and others. ar_model : univariate autoregressive process, estimation with conditional and exact maximum likelihood and conditional least-squares Last modified: Jan 26, 2025 By Alexander Williams Cointegration is a key concept in time series analysis.

It helps identify long-term relationships between variables. The coint() function in Python's Statsmodels library is a powerful tool for this purpose. This guide will walk you through the basics of using coint(). You'll learn its syntax, how to interpret results, and see practical examples. Let's dive in! Cointegration refers to a statistical relationship between two or more time series.

Even if individual series are non-stationary, their linear combination can be stationary. This implies a long-term equilibrium relationship. For example, stock prices and dividends may be cointegrated. While both series may trend over time, their relationship remains stable. Cointegration is crucial in econometrics and finance.

I am trying to understand how to apply cointegration.

I got the intution behind cointegration but can't understand what coint output value means or how to use it? I know statsmodels.tsa.stattools.coint output returns coint,p value and Critical values. I know about pvalue but I want to understand the application of coint values. statsmodels.tsa contains model classes and functions that are useful for time series analysis.
