Trends analysis


New Member

Which is the most appropriate method to use when we are trying to assess trends over time for a nominal multicategory variable?
For example, if I want to examine if there is a trend over 10 years in composition of population by their insurance status who makes a hospital visit. So variable 1= insurance (pvt insurance, medicaid, medicare, uninsured) as proportions and other variable is the 10 years (2000-2009). Is Cochrane Mantel Haenszel the correct test? If so, which one among the three statistics it computes should I use in such a situation?

Thanks in advance!
