- Price: 1.99

This mobile application combines a selection of the most frequently needed epidemiological calculations, such as measures of effect and association, diagnostic test evaluation, and sample size calculations. The App includes calculations of relative risk and odds ratios, risk difference and population attributable fraction, among others. Diagnostic sensitivity and specificity, predictive values and likelihood ratios can be calculated from 2x2 tables, and the effect of prevalence on thes parameters visualised in graphs. Sample size calculations for trials are made easy by this tool, as is the calculation of sample size required for detection of a condition, or disease, as well as for detecting differences.

- Develve
- License: Shareware
- Price: 79

Statistical software for fast and easy interpretation of experimental data in science and R&D in a technical environment. This statistical package helps with analysis and prevents making false assumptions. In short it makes statistics faster and easier, suitable for less experience users but advanced enough for more demanding users. Develve has no deep hidden menus, everything is directly accessible and the results are directly visible, to improve the productivity. For instance the result graphs are easily scrollable and with a click on a graph a bigger version will pop up. Develve clearly indicates when two data groups are significantly different, and if the sample size is big enough to prevent false assumptions.

Sample size required in tests concerning the variance, employing the Chi-square distribution and solved by iterative fashion (directed trial and error). This means that we enter an initial value for n in order to obtain a better estimate. It only needs the sample variance, expected (hypothesized) variance, initial sample size, hipothesis direction, Type II error and significance level..

- Sequential analysis
- License: Shareware

In statistics, sequential analysis or sequential hypothesis testing is statistical analysis where the sample size is not fixed in advance. Instead data is evaluated as it is collected, and further sampling is stopped in accordance with a pre-defined stopping rule as soon as significant results are observed. Thus a conclusion may sometimes be reached at a much earlier stage than would be possible with more classical hypothesis testing or estimation, at consequently lower financial and/or human cost.

Biometrics. 1952; 8:186 Syntax: seqanalysis(x) Inputs: X - Nx2 data matrix Outputs: - Sequential analysis plots Example: During a sperimentation between two terapies, two drugs A and B were administered to patients couples (one received A, the other B).

- Power Analysis for T-tests
- License: Shareware

The main function, TPOWER, will compute the power of a t-test given an effect size (d), sample size (N), and alpha. By giving N as an array the program can be used to plan sample size for an experiment. By setting the "PLOT" parameter to 1 the function calls plotpowfun, which plots the array N against power. By providing a desired power level, DESPWR, the program will also determine the minimum sample size needed to reach the desired power..

Power your study designs wherever you go.
GLIMMPSE Lite is a free, user-friendly and open source smart-phone application which allows students, researchers, and statisticians to calculate power and sample size for one way analysis of variance.
The simple user interface allows scientists to quickly enter information about the number of groups, the Type I Error rate, and choices for means and standard deviations. Integrated tutorials provide guidance on appropriate
inputs for the power or sample size calculation. The researcher may solve for either power or sample size, and save the results.

- (Sample) Size Matters
- License: Freeware

Social science has uncovered many fascinating aspects of human behavior, from how we think as individuals to how we act in groups. We know that humans are loss averse, emotional, habit-forming creatures. We mispredict the future and misremember the past. And yet, what social science is missing is a better understanding of how these phenomena (and others) change over time, in different cultures and regions, across gender and age.
By collecting a heaping amount of data (and increasing the size of our samples), we hope to unravel nuances in behavioral variations; we hope to detect the impact of minor differences that simply wouldn’t appear in smaller samples.

LinStats is a collection of classes, functions and data that are useful for representing, solving and analyzing linear statistical models. LinStats has been updated to use a new object based approach to support incremental model-building and more sophisticated analysis. Notably this is the first Matlab statistical package that can handle ANOVA and Variance Components models with fixed and random effects using Restricted Estimated Maximum Likelihood (REML) including the modern corrections for small sample size. This allows improved estimates for both fixed (Best linear unbiased estimates) and random terms (Best linear unbiased predictors).
