Statistics Advisor

Not sure which test to run? Neither is half the lab.

SigmaPlot’s Advisor asks what you want to find out, suggests the right test, checks the assumptions in the background and writes a report you can actually read. Try a simplified version here.

A simplified illustration. SigmaPlot’s Advisor also tests normality and equal variance on your actual data.

Dynamic curve fitting

Let it try 200 starting points, so you don’t have to.

Non-linear fits can get stuck on a poor answer when the starting values are off. SigmaPlot’s Dynamic Curve Fitter runs the fit from many starting points, ranks the results by goodness of fit and gives you the best one.

  • Four- and five-parameter logistic curves for dose-response
  • EC50, and EC values beyond it such as EC40 and EC60
  • Global fitting across several datasets with shared parameters
  • Your own equations next to the built-in library

Example data, fitted in your browser to show the idea.

SigmaPlot or Excel

Keep Excel for the data. Use SigmaPlot for the figure.

SigmaPlot works with Excel instead of replacing it: start the Graph Wizard from the Excel toolbar and keep your formulas, pivot tables and macros.
