BioStat 2008 5.2.5.0

BioStat 2008 5.2.5.0 is a user-friendly and very complete biology and medicine oriented statistical software. With BioStat 2008, one gets a robust suite of statistics tools and graphical analysis methods that are easily accessed though a simple and straightforward interface. While BioStat 2008 is a "heavy-duty" biology and medicine oriented professional statistical analysis tool, the interface is so simple that even people who have no knowledge of statistics are capable of processing data, provided they know how to use PC and clear instructions are given. This frees up intellectual resources for analyzing the results, rather than agonizing over who and how processed the data, and if any mistakes were made in the process.

Major Features: 

1. Basic statistics:
   • determining descriptive statistics

   • cross-tabulation
   • frequency tables analysis
2. ANOVA (MANOVA, GLM ANOVA)
   
3. Nonparametric statistics:
   • 2x2 Tables Analysis (Chi-square, Yates Chi-square, Exact Fisher Test, etc.)
   • rank correlations (Kendall Tau, Spearman R, Gamma, etc.)
   • comparing independent samples (Mann-Whitney U Test, Kolmogorov-Smirnov test, Wald-Wolfowitz Runs Test, Rosenbaum Criterion; Kruskal-Wallis ANOVA, median test)
   • comparing dependent samples (Wilcoxon Matched Pairs Test, Sign Test, Friedman ANOVA, Kendall's Coeff. of Concordance)
   • Cochran Q Test
4. Regression analysis:
   • multivariate linear regression
   • logistic regression
   • stepwise regression
   • polynomial regression
   • Cox proportional-hazards regression
5. Time series analysis
