A short video demonstrating how to test whether a collection of data can be statistically distinguished from a sample drawn from a normal distribution. Nothing in this question looks unique to econometrics. Is the distribution of the detrended global temperature anomalies 'normal'? I've been meaning to test this. One still occasionally gets whinging from some corner or other about not being able to run Analysis of Variance statistical procedures (ANOVA) because the data didn't pass a test of normality. St: RE: [question about testing for normality]. In this module, we will cover some basics about normal distribution. Before you begin to analyze your data, it is important to check the assumptions associated with each statistical procedure. The normality test gives p=0.13, which is large, so we do not reject the null hypothesis that the values are distributed normally. Which is to say, do the residuals around the OLS trend assume a gaussian distribution? One can check the normality assumption by means of the posterior predictive distribution. Using the Anderson-Darling Normality test helps to determine if different sets of data are normally distributed. We will discuss what a normal distribution is and how to check if the data is normally distributed. Here's an outline of the approach. Next check the Shapiro-Wilk test of normality. This test is carried out in SPSS. Please use informative titles for your posts. On the New Algorithm of Testing and Comparing Size Corrected Powers for Testing Multivariate Normality. (There are special functions in the LearnBayes package that make this process simple to implement.).
