Power comparisons of Shapiro-Wilk , Kolmogorov-Smirnov , Lilliefors and Anderson-Darling tests

  title={Power comparisons of Shapiro-Wilk , Kolmogorov-Smirnov , Lilliefors and Anderson-Darling tests},
  author={Nornadiah Mohd Razali and Yap Bee Wah},
The importance of normal distribution is undeniable since it is an underlying assumption of many statistical procedures such as t-tests, linear regression analysis, discriminant analysis and Analysis of Variance (ANOVA). When the normality assumption is violated, interpretation and inferences may not be reliable or valid. The three common procedures in assessing whether a random sample of independent observations of size n come from a population with a normal distribution are: graphical methods…

Power Comparisons of Normality Tests Based on L-moments and Classical Tests

Normality tests are used in the statistical analysis to determine whether a normal distribution is acceptable as a model for the data analysed. A wide range of available tests employs different

On empirical power of univariate normality tests under symmetric, asymmetric, and scaled distributions

The study aims at conducting an empirical comparison of powers of the univariate normality tests under different distributions to obtain their ranking using a Monte-Carlo simulation for large sample

Comparing the performance of normality tests with ROC analysis and confidence intervals

The Shapiro–Wilk test was seen to have the best global performance overall, though in some circumstances the Shapiro–Francia or the D'Agostino tests offered better results, and the differences between the tests were not as clear for smaller sample sizes.

Shapiro–Francia test compared to other normality test using expected p-value

The Shapiro–Francia (SF) normality test is an important test in statistical modelling. However, little has been done by researchers to compare the performance of this test to other normality tests.

Power analysis of several normality tests: A Monte Carlo simulation study

Abstract In statistical inference, oftentimes the data are assumed to be normally distributed. Consequently, testing the validity of the normality assumption is an integral part of such statistical

Comparison of conventional measures of skewness and kurtosis for small sample size

The normality assumption can be checked in three ways: graphical methods (histogram, normal Q-Q plot, and boxplots), descriptive statistics (value of skewness and kurtosis) or conducting test of

Omnibus test for normality based on the Edgeworth expansion

A novel approach to the problem of testing normality is developed by constructing a statistical test based on the Edgeworth expansion, which approximates a probability distribution in terms of its cumulants.

Abstract The first aim of the paper is to put into practice the -corrected Lilliefors goodness-of-fit test for normality (LF). This modification consists in varying a formula of calculating the

The Comparison Of Hypothesis Tests Determining Normality and Similarity Of Samples

A number of hypothesis tests are used to obtain information about the characteristics of one or more populations. While parametric tests are based on the assumption of normal distribution,

The Power to See: A New Graphical Test of Normality

A simple new graphical procedure is discussed which provides simultaneous confidence bands for a normal quantile–quantile plot which define a test of normality and are narrower in the tails than those related to the Kolmogorov–Smirnov test.



Investigation of Four Different Normality Tests in Terms of Type 1 Error Rate and Power under Different Distributions

The Jarqua-Bera test was superior for normal and standard normal distributions and for nonnormal distributions, achieving sufficient power at smaller sample sizes, the Shapiro-Wilk was the most powerful.

Detecting Departures from Normality: A Monte Carlo Simulation of a New Omnibus Test Based on Moments.

The assumption of normality underlies much of the standard statistical methodology. Knowing how to determine whether a sample of measurements is from a normally distributed population is crucial both

Comprehensive study of tests for normality and symmetry: extending the Spiegelhalter test

Statistical inference in the form of hypothesis tests and confidence intervals often assumes that the distribution(s) being sampled are normal or symmetric. As a result, numerous tests have been

An Analysis of Variance Test for Normality (Complete Samples)

The main intent of this paper is to introduce a new statistical procedure for testing a complete sample for normality. The test statistic is obtained by dividing the square of an appropriate linear

A comparison of various tests of normality

This article studies twelve different normality tests that are used for assessing the assumption that a sample was drawn from a normally distributed population and compares their powers. The tests in

Type I Error Rate and Power of Three Normality Tests

Shapiro-Wilks, Lilliefors and Kolmogorov-Smirnov test results were the weakest among all three tests, but all three test were most powerful when ran on data with exponential distribution.

On the Kolmogorov-Smirnov Test for Normality with Mean and Variance Unknown

Abstract The standard tables used for the Kolmogorov-Smirnov test are valid when testing whether a set of observations are from a completely-specified continuous distribution. If one or more

Algorithm AS 181: The W Test for Normality

The purpose of the present algorithm is to enable the calculation of the Shapiro and Wilk Wstatistic and its significance level for any sample size between 3 and 2000.

An Extension of Shapiro and Wilk's W Test for Normality to Large Samples

Shapiro and Wilk's (1965) W statistic arguably provides the best omnibus test of normality, but is currently limited to sample sizes between 3 and 50. W is extended up to n = 2000 and an approximate
