Enter different equations for different data sets.

Enter differential or implicit equations.

Now including family of growth equations: exponential growth, exponential plateau, Gompertz, logistic, and beta (growth and then decay).

Fit one of our 105 built-in equations, or enter your own.

Comparison of data from nested data tables using nested t test or nested one-way ANOVA (using mixed effects model).

Analysis of repeated measures data (one-, two-, and three-way) using a mixed effects model (similar to repeated measures ANOVA, but capable of handling missing data).

Three-way ANOVA (limited to two levels in two of the factors, and any number of levels in the third).

Tukey, Newman-Keuls, Dunnett, Bonferroni, Holm-Sidak, or Fisher’s LSD multiple comparisons testing main and simple effects.

Two-way ANOVA, with repeated measures in one or both factors.

Two-way ANOVA, even with missing values with some post tests.

Calculate the relative risk and odds ratio with confidence intervals.

Fisher's exact test or the chi-square test.

Kruskal-Wallis or Friedman nonparametric one-way ANOVA with Dunn's post test.

When this is chosen, multiple comparison tests also do not assume sphericity.

Greenhouse-Geisser correction so repeated measures one-, two-, and three-way ANOVA do not have to assume sphericity.

Many multiple comparisons test are accompanied by confidence intervals and multiplicity adjusted P values.

One-way ANOVA without assuming populations with equal standard deviations using Brown-Forsythe and Welch ANOVA, followed by appropriate comparisons tests (Games-Howell, Tamhane T2, Dunnett T3).

Ordinary or repeated measures 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.

Perform many t tests at once, using False Discovery Rate (or Bonferroni multiple comparisons) to choose which comparisons are discoveries to study further.

Wilcoxon test with confidence interval of median.Kolmogorov-Smirnov test to compare two groups.Nonparametric Mann-Whitney test, including confidence interval of difference of medians.Automatically generate volcano plot (difference vs.
