Contents Evaluation of regression coefficients Evaluation of the model Regression Estimation Evaluation of regression coefficients T tests in regression analysis tests for the following null hypothesis (H0) for the regression coefficients of the generated model: H0: No significant difference by coefficient These results indicate that the test statistic, t, is outside the confidence interval and that the p-value is also close to zero, which is much lower than the significance level. Therefore, the results for the above dollor index indicate that the null hypothesis cannot be adopted. This discussion can be generalized as follows: The calculated regression coefficients also form a distribution as probability variables, so you can conduct a test. As mentioned above, the distribution has the same shape as the distribution of errors, so you can calculate the variance of the regression coefficient based on the variance of the error. As shown in Equation 1, the regression...
