Tests For Correlation On Bivariate Nonnormal Distributions, Louanne Margaret Beversdorf
UNF Graduate Theses and Dissertations
Many samples in the real world are very small in size and often do not follow a normal distribution. Existing tests for correlation have restrictions on the distribution of data and sample sizes, therefore the current tests cannot be used in some real world situations.
In this thesis, two tests are considered to test hypotheses about the population correlation coefficient. The tests are based on statistics transformed by a saddlepoint approximation and by Fisher's Z-transformation. The tests are conducted on small samples of bivariate nonnormal data and found to perfom well.
Simulations were run in order to compare the type …
