Incidence rate confidence interval
Some interval estimates would include the true population parameter and some would not. A 90% confidence level means that we would expect 90% of the interval estimates to include the population parameter; a 95% confidence level means that 95% of the intervals would include the parameter; and so on. Statistics and probability. Confidence intervals. Skill Summary Legend (Opens a modal) Introduction to confidence intervals. Estimating a population proportion. Confidence intervals give us a range of plausible values for some unknown value based on results from a sample. This topic covers confidence intervals for means and proportions. A 99% confidence interval for the proportion in the whole population having the same intention on the survey might be 30% to 50%. From the same data one may calculate a 90% confidence interval, which in this case might be 37% to 43%. For example, confidence intervals with confidence of 80 percent will, in the long run, miss the true population parameter one out of every five times. Any number from zero to one could, in theory, be used for a confidence level. In practice 90 percent, 95 percent and 99 percent are all common confidence levels.

Wald confidence interval for the incidence rate ratios for each strata.
Events observed = 14 Time at risk of event = 400 Poisson (e.g. incidence) rate estimate = 0.035 Exact 95% confidence interval = 0.019135 to 0.058724 Here we can say with 95% confidence that the true population incidence rate for this event lies between 0.02 and 0.06 events per person year.
