GraphPad Prism is a handy and reliable application designed for experimental biologists and drug companies in order to combine scientific graphs, understandable statistics and data organization.

Prism has all the capabilities you would expect from a top notch scientific graphics program, but what makes Prism truly unique is not what it does, but how it does it. Designed for the practical scientist, Prism does not expect you to be a statistician. It guides you through each analysis - giving you as much help as you need - and tracks and organizes your work like no other program available. You can concentrate on your data, not fight with your software

Nonlinear regression is an important tool in analyzing data, but is often more difficult than it needs to be. No other program simplifies curve fitting like Prism. In fact, you can usually fit curves in a single step.

Just select an equation from the extensive list of commonly used equations (or enter your own equation) and Prism does the rest automatically -- fits the curve, displays the results as a table, and draws the curve on the graph. Even better, Prism will automatically fit all related data sets at once. You don't have to repeat commands for each experimental condition.

Features:

· Perform many tests at once, using False Discover Rate to choose which comparisons are discoveries to study further.
· Ordinary or repeated measures one-way ANOVA followed by the Tukey, Newman-Keuls, Dunnett, Bonferroni or Holm-Sidak multiple comparison tests, the post-test for trend, or Fisher’s Least Significant tests.
· Calculate min, max, quartiles, mean, SD, SEM, CI, CV.
· Mean or geometric mean with confidence intervals.
· Frequency distributions (bin to histogram), including cumulative histograms.
· Normality testing by three methods.
· Robust nonlinear regression.
· Automatic outlier identification or elimination.
· Compare models using extra sum-of-squares F test or AICc.
· Compare parameters between data sets.
· Apply constraints.
· Differentially weight points by several methods.
· Accept automatic initial estimated values or enter your own.
· Automatically graph curve over specified range of X values.
