Probability Plot Correlation Coefficient R. On the table find the row corresponding to the size n n of your data set. Most of the statistical analysis has been done assuming the shape of the distribution in mind.
Where the correlation coefficient r r given above is the test statistic. Linear Correlation Analysis Reference. This technique is appropriate for families such as the Weibull that are defined by a single shape parameter and location and scale parameters and it is not appropriate for distributions such as the normal that are defined only by location and.
Most of the statistical analysis has been done assuming the shape of the distribution in mind.
0 indicates a negative association. The probability plot correlation coefficient test consists of two widely used tools in water resource engineering. 0 indicates a positive association. Many water resource applications require powerful hypothesis tests for nonnormal distributions.
