GraphPad Prism 5.0
Features of GraphPad Prism
Curve fitting
- Marquardt-Levenberg nonlinear regression.
- Fit data to a built-in classic equation, choose from an equation library, or enter your own.
- Built-in
equations include kinetic equations (exponential decay, growth,
association), equilibrium mass action equations (binding isotherm,
sigmoidal dose-response, competitive binding including 2 site),
polynomial up to 4th order, Gaussian distribution, power series and
sine.
- Enter multiple-line user-defined equations, including
If-Then clauses. Define different equations for different data sets
(columns).
- Generate a family of theoretical curves.
- Create equation libraries to distribute to others.
- Fit data to two equations and compare fits with an F test. Automatically graph the best fit.
- Fit several data sets at once, sharing selected parameters between the data sets.
- Compare
two curves by comparing the sum of squares when selected parameters are
shared between the data sets with the individual sum of squares.
- Compare models (and data sets) using the extra sum-of-squares F test or Akaike's Information Criterion (AIC).
Data management
- Enter Y data as raw replicates or mean, SD/SEM and N.
- Automatic updating of analyses and graphs as data change.
- Enter
up to 104 related data sets on one table to be analyzed and plotted
together. Up to 52 replicates and any number of points per data set
- Accurately accounts for missing values.
- Exclude
specified points from analyses and graphs (they show on the table in
blue italics, but are ignored by the analyses and graphs).
- Transfer data to and from Excel and other applications with the clipboard, or import and export text (ASCII) files.

- Transform data with a full range of mathematical functions, including user-defined transforms.
- Smooth curves, or convert to their derivative or integral.
Statistics

- Specify desired level of confidence.
- Frequency distributions (bin to histogram), including cumulative histograms.
- Kolgoromov-Smirnov normality test.
- One sample t test or Wilcoxon test to compare the column mean (or median) with a theoretical value.
- Skewness and Kurtosis.
- Kaplan-Meier survival analysis. Compare curves with the log-rank test (including test for trend).
- Paired or unpaired t tests.
- Mann-Whitney or Wilcoxon tests.
- Ordinary
or repeated measures one-way ANOVA with Tukey, Newman-Keuls, Dunnett or
Bonferroni post tests, or the post-test for trend.
- Kruskal-Wallis or Friedman nonparametric one-way ANOVA with Dunn's post test.
- Fisher's exact test or the chi-square test. Calculate the relative risk and odds ratio with confidence intervals.
- Two-way ANOVA, even with missing values with some post tests.
- Repeated measures two-way ANOVA with some post tests.
- Bland-Altman plots.
- Receiver operator characteristic (ROC) curves.
- Deming regression (type ll linear regression).
Graphing
- Linear, log10, or log2 scale, ascending or descending numbering.
- Segment axes with up to two breaks (gaps) per axis.
