Hello.
I am using the Myanmar DHS 2015-16 data to identify the determinants of contraceptive use among 15-19 and 20-24 married women. The observations selected was "15-19 = 235" and "20-24 = 859".
Svyset was used. The independent variables are the socio-demographic and other variables like exposure to family planning messages. The dependent variable is "modern contraceptive use".

On using the "svy, subpop ( ), tab" command to analyze the two age groups separately, some of the cells become either 0 or lower than 5.

Variable --> v013 - 15-19 = 1
- 20-24 = 2

Questions
1. The cells with 0 observations showed a message "Table contains a zero in the marginals. Statistics cannot be computed". I used the command "svy if v013==1, tab" command and the 0 disappeared. The proportions and confidence interval are the same but I got the p-value. However, is it recommended to use this command or is there an alternative?

2. Some cells have observations less than 5. Usually Fisher's exact test is used in very small numbers but in this survey set, it is not compatible (I think). Is there a way to calculate them?
