WebFeb 14, 2024 · Box-Ljung test data: data X-squared = 6.0721, df = 10, p-value = 0.8092 The test statistic of the test is Q = 6.0721 and the p-value of the test is 0.8092, which is much larger than 0.05. Thus, we fail to reject the null hypothesis of the test and conclude that the data values are independent. WebIn statistics, a Q–Q plot (quantile-quantile plot) is a probability plot, a graphical method for comparing two probability distributions by plotting their quantiles against each other. A point (x, y) on the plot corresponds to one of the quantiles of the second distribution (y-coordinate) plotted against the same quantile of the first distribution (x-coordinate).
