Here are some key features of "ClinTools":

· Effect Size Generator
· Compute: Cohen's d; Hedges' Adjustment for sample size (to Cohen's d); Hedges' ĝ effect size estimate; 95% confidence intervals; pooled and other standard deviation estimates; independent samples t-tests and z statistic; a priori power analysis; effect size conversions (many - w to C, d to ĝ, ĝ to r, F to d, f2 to R2, r to d, etc, etc) with and without sample size corrections; compute confidence intervals around mean (any confidence interval!); compute effect size interactions on repeated measure analysis; estimate f2 effect size estimates for both multiple and hierarchical regressions; conduct 2x2, 2x3 and 3x3 Chi Square analyses; test difference between effect sizes; Help files explaining all effect size statistics used.
· Conduct meta-analyses allowing: unweighted and weighted mean effect size estimates; Rosenthal's Fail-Safe N statistic; Orwin's Criterion d and g; computation based upon measure type; computation based upon study type; tests of heterogeneity (Q and I-Squared statistics); complete summary information in text file format; conversion of files to MS Access and Excel format; Help files explaining all statistics used.
· Odds Ratio Generator
· Relative Risks; Relative Risk Increases; Event Odds; Odds Ratios; Number Needed To Treat; Number Needed To Harm; 95% confidence intervals; Chi Square Analysis (2*2 and 2*3); Yates' Correction; Fisher's Exact Test; Phi / Cramer's Phi; Convert Odds Ratios to d effect sizes; Help files explaining statistics behind programme.
· Improvement vs no change vs deterioration; improvement vs no improvement; for treatment and control groups.
· Reliable & Clinical Change Generator
· Reliable change indices with 68.26%, 95% or 99% confidence; whether there has been change with 68.26%, 95% or 99% confidence.
· Clinical change as measured by: moving from 1.96 sd above the norm to within 1.96 sd of the norm; moving from within 1.96 sd of the clinical mean to 1.96 sd below the clinical mean; moving above the 'compromise' point to below this point.
· The necessary change required for any level of confidence.
· Random Number Generator.
· Compute up to 32,767 random numbers between any given range; unique random numbers or repeated random numbers; Randomly allocate participants to experimental groups.
· Export results to comma delimited text file for easy importation to other statistical packages such as SPSS and Statistica.
