  • Confidence interval for crude rate

    I would like to calculate the 95% confidence interval for the crude rate. How I could do it in STATA?

    Also, if I would like to calculate the 95% CI for the overall age-standardized incidence rate. How I can do it in STATA?

        Thank you Carlo. If I have only the age standardised incidence rate and I don’t have the complete data set. could you please let me know how I can estimate the 95% CI for the age standardised incidence rate?

          I would consider -bootstrap-ping the SIR to calculate its 95% CI.

            Thank you Carlo.

            I used the STATA code to calculate age-standardised rate(ASR), but it did not give me the overall ASR and the 95% confidence interval for the overall ASR.

            my code for the direct age-standardised rate (ASR) as below:

            dstdize cases pop age_group, by(age_group)

            Could you please help me how I can get the overall of the ASR from the STATA.

            Many thanks

              Elias:
              as there's no way to kick -by()- out the -dstdize- code, you can create a -newvar-=1 and plug in between -by()- brackets.
              Kind regards,
