WebJan 22, 2024 · To test if the slope coefficient is statistically significant, we can calculate the t-test statistic as: t = b 1 / se(b 1) t = 2.7037 / 0.7456; t = 3.626; The p-value that corresponds to this t-test statistic is shown in the column called Pr(> t ) in the output. The p-value turns out to be 0.00464. WebMar 20, 2013 · Delete it: > > t.stat <- coef (fit)/se Note though that this is a z ratio, not a 't-stat', whatever that is. Its utility is moot: coefficients of ARMA models are constrained, and if there is more than one, quite a long way from independent. You cannot use this for a test statistic nor for a confidence interval.
