Hi Ubydul, under certain assumptions that might be correct; you have given us very little information so you must make your own assumptions (e.g., is it reasonable to assume that the number at risk of being a "case" was the same each year?); note that (1) there should be no space between level and the open parenthesis and (2) since 95 is the default, there is no need for this option at all unless you want a different value Rich On 9/16/13 4:33 PM, Ubydul Haque wrote: > Hi Richard, > Is it something like cii 675 168, level (95) in STATA?
