MS-Windows

Software for sample size estimation, evaluation of diagnostic tests (incl. ROC analysis), cross-tabulation of data from various types of epidemiological studies, Reed-Frost simulation models.
FreeCalc

2.0

Windows Epidemiological calculator for planning and analysis of surveys to detect disease or prove freedom from disease; calculates sample size requirements based on diagnostic test sensitivity and specificity, taking population size into account, and analyses the results of such surveys
G*Power

2.0

MS-DOS,
Macintosh
Statistical power analyses for the most common statistical tests t-tests; post hoc, a priori and compromise power analyses.
Herdacc 3.0 MS-Windows Program for calculating herd (aggregate) sensitivity and specificity for a wide range of values of individual level sensitivity and specificity
PS 2.1.31
MS-Windows Interactive program for performing power and sample size calculations. It can be used for studies with dichotomous, continuous, or survival response measures. The alternative hypothesis of interest may be specified either in terms of differing response rates, means, or survival times, or in terms of relative risks or odds ratios.

SampleXS   MS-Windows Sample size calculator for cross-sectional surveys using simple random, systematic, or complex samples
SSize   Palm Calculates sample size using either power or confidence interval widths for a variety of distributions with respect to linear models, and for a variety of specialized situations such as  for logistic models and contingency tables
Survey Toolbox 1.03 Windows 95 Suite of software programs which are designed to make planning, conducting and analysing statistically valid, efficient and practical animal health surveys easier
