Table test statistic
WebIn the last years minimum phi-divergence estimators (MϕE) and phi-divergence test statistics (ϕTS) have been introduced as a very good alternative to classical likelihood ratio test and maximum likelihood estimator for different statistical problems. The main purpose of this paper is to present an overview of the main results presented until now in … WebDec 27, 2024 · From the output table we see that the F test statistic is 2.358 and the corresponding p-value is 0.11385. Since this p-value is not less than 0.05, we fail to reject the null hypothesis. This means we don’t have sufficient evidence to say that there is a statistically significant difference between the mean exam scores of the three groups.
