Epitools Sample Size. Tools for training and practicing epidemiologists including methods for two-way and multi-way contingency tables. Our multidisciplinary team works with terrestrial and aquatic animals humans plants and OneHealth.
The results are presented as. Calculate sample sizes for 2-stage surveys for demonstrating disease freedom for specified target cluster-level sensitivity and system population sensitivity. Least cost sample size with unknown cluster sizes.
Sample size calculation for fixed pool size and uncertain sensitivity and specificity Sample size calculations Sample size for a case-control study Sample size for a cohort study Sample size for demonstration of freedom detection of disease using pooled testing Sample Size for survival analysis to compare median times since last outbreak.
This analysis calculates the number of clusters and the number of units within each cluster to be tested to. Sample size calculation for fixed pool size and uncertain sensitivity and specificity Sample size calculations Sample size for a case-control study Sample size for a cohort study Sample size for demonstration of freedom detection of disease using pooled testing Sample Size for survival analysis to compare median times since last outbreak. Sample Size for survival analysis to compare median times since last outbreak Sample size required to achieve target confidence of freedom Sample size to achieve specified population level or herd flock cluster etc sensitivity Sample size to detect a significant difference between 2 means with equal sample sizes and variances. Feb 16 2018 Lets explore the use of one of the Epitools listed in the flow chart above.
