Abstract

The article presents research which assessed the efficiency of statistical tests for examining the trend curves when used in national immunization survey (NIS). It mentions that the Chi-square and the Z test statistics were developed for large sample size that has independent normal assumption across consecutive time points and among strata. On the other hand, the F-test statistic is commonly used when assessing surveys with a small sample size with independent normal assumption.
