WebMar 5, 2016 · Several goodness-of-fit tests, such as the Anderson-Darling test and the Cramer Von-Mises test, are refinements of the K-S test. As these refined tests are generally considered to be more powerful than the original K-S test, many analysts prefer them. WebMay 16, 2024 · Each value denotes the count of accidents in one month. The actual dataset has 50 values that cover 50 months. To determine whether these data follow the Poisson distribution, we need to use the Chi-Squared Goodness-of-Fit Test for the Poisson distribution. The statistical output for this test is below.
WebFor construct validity, exploratory factor analysis was used to assess factor structure, and confirmatory factor analysis was used to evaluate the structural model fit of the scale.RESULTS: Reliability was confirmed by internal consistency (Cronbach α = 0.79) and test-retest reliability (intraclass correlation coefficient, 0.88).
