Hi, I have a similar question like this. After doing this step, how could I interpret the 0.4463? What is the trend for the data? Since the prevalence or the incidence are not normally distributed, could I just use Simple Regression Model and get the coefficient for the trend? Or is there any other suggestion for this situation? I have a sample data like below. Thanks a lot. Kendall Tau b Correlation Coefficients, N = 41 Prob > |tau| under H0: Tau=0 Year Prevalence 0.44634 <.0001 Year Prevalence 1974 16.943 1975 19.6 1976 18.934 1977 18.48 1978 19.924 1979 12.369 1980 17.302 1981 15.954 1982 16.75 1983 17.184 1984 17.722 1985 19.008 1986 18.452 1987 16.744 1988 17.029 1989 17.643 1990 17.179
