The t-statistic is commonly used to test hypotheses about individual regression coefficients. It measures the difference between the estimated coefficient value and the hypothesized value in terms of the estimated standard error of the coefficient. By comparing the t-value to the critical t-value, we can determine whether the coefficient is statistically significant at a given level of significance.
