Veterinary epidemiology: software associated with probability distributions
Many statistical tests (along with both frequentist and Bayesian methodologies) are based upon probability distributions. The following programs allow these to be investigated further:
NCSSCALC (Allows the investigation of various probability distributions, for example to estimate the probability of a particular outcome) http://www.ncss.com/download_probcalc.html
p-value [direct link to software] (Statistical utility program for computing p-values from probability distributions under standard hypothesis tests) http://www.vetschools.co.uk/EpiVetNet/files/pvalue10.zip
Simtools (Allows random sampling from various distributions, which can be useful for risk analysis and Monte Carlo simulation. Also facilitates decision analysis and regression modelling) http://home.uchicago.edu/~rmyerson/addins.htm
Tables (A programme containing 42 statistical distributions. For each, in addition to the percentage points and their inverses, there is an extensive help, a plot of the density, a mechanism for generating random values, and various descriptive statistics) http://www.bobwheeler.com/statistics/StatisticalTables/statisticaltables.html
BetaBuster (allows the parameterisation of Beta distributions based on the desired qualities of the distribution) http://www.epi.ucdavis.edu/diagnostictests/betabuster.html
