Intervalos de confianza de Agresti-Coull
The Agresti-Coull confidence interval is a statistical method used to estimate the true proportion of a certain characteristic in a population based on a sample. It adjusts the usual calculation to account for small sample sizes or when the proportion is very close to 0 or 1, making the estimate more reliable. Essentially, it provides a range of values within which the actual proportion is likely to fall, with a specified level of confidence (like 95%). This interval helps researchers understand the uncertainty around their sample estimate and make more accurate conclusions about the entire population.
