Enter differential or implicit equations.Enter different equations for different data sets.Global nonlinear regression – share parameters between data sets.Automatic outlier identification or elimination.Compare models using extra sum-of-squares F test or AICc.Differentially weight points by several methods and assess how well your weighting method worked.

Accept automatic initial estimated values or enter your own.Automatically graph curve over specified range of X values.

Quantify precision of fits with SE or CI of parameters.

Quantify symmetry of imprecision with Hougaard’s skewness.Ĭonfidence intervals can be symmetrical (as is traditional) or asymmetrical (which is more accurate).

Create QQ Plot as part of normality testing.Lognormality test and likelihood of sampling from normal (Gaussian) vs.Normality testing by four methods (new: Anderson-Darling).Frequency distributions (bin to histogram), including cumulative histograms.Mean or geometric mean with confidence intervals.Calculate descriptive statistics: min, max, quartiles, mean, SD, SEM, CI, CV, skewness, kurtosis.Fit straight lines to two data sets and determine the intersection point and both slopes.Easily interpolate points from the best fit curve.Report the covariance matrix or set of dependencies.Runs or replicates test of adequacy of model.
