Abstract
This study looked into the incidence of heart disease in Tamilnadu between January 1, 2016, and December 31, 2020. Heart disease cases have been found to be positively correlated with one another. The Granger causality tests used in the Breusch-Godfrey LM approach for testing, residual serial auto correlation assumes a VAR model for the error vector _t, while the contrary was not true. can be determined using common model selection criteria such as the Final Prediction Error, Hannan-Quinn Information Criterion, Schwarz Information Criterion, and Akaike Information Criterion (FPE) time series plots, the Augmented Dickey Fuller (ADF) test, the Philip Perrons (PP) test, and the Kwiatkowski-Phillip-Schmidt-Shin test, determine the series' stationarity (KPSS) test. For both the ADF test and the PP test. The OLS-CUSUM test for stability.
