Similarly, youД¬an easily check if error bars represent the SD or SEM (orДЄll parts of your Prism project are linked. Transformed to logarithms before the curve was fit). Someone else, you can review (and change) all analysis choices, and It isnвЂ™t really science unless you can document exactly how yourДata were analyzed. Your experimental design, and that you understand the assumptions Once youвЂ™ve completed the analysis, PrismвЂ™s unique analysisД¬hecklists help you make sure you chose an analysis appropriate for Teach you what you need to know to appropriately analyze your More than half of it is devoted to thoroughД®xplanations of basic statistics and nonlinear curve fitting, to The Prism documentation goes beyond anything Your choices, Prism presents the results on organized,Д®asy-to-follow tables. Press 'Learn' from any data analysis dialogДЄnd Prism's online documentation will explain the principles of theДЄnalysis to help you make appropriate choices. Unlike other programs, Prism provides understandable statistical AnalysisД¬hoices are presented in clear language that avoids unnecessary Nonparametric comparisons, one-, two- and three-way ANOVA,ДЄnalysis of contingency tables, and survival analysis. You easily perform basic statistical tests commonly used by While it won't replace a heavy-duty statistics program, Prism lets

Weight data points, test residuals for normality, and much The fits of two equations using an F test or Akaike's InformationД¬riterion (AIC), plot residuals, identify outliers, differentially Values from a standard curve (i.e., to analyze RIA data), compare It can also automatically interpolate unknown Method), which are far more accurate than the usual symmetrical The best-fit parameters as asymmetrical ranges (profile likelihood It can report the confidence intervals of Prism also gives you manyДЄdvanced fitting options. Nonlinear regression to share parameter values among data sets, orДЇit different models to different data sets.Дon't be fooled by the simplicity. You canДЇit the same model separately to each data set, use global Table, and Prism can fit them all the data sets at once. Place data for multiple data sets side-by-side on an organized data Results as a table, draws the curve on the graph, and interpolates Prism does the rest automatically - fits the curve, displays the

List of commonly used equations (or enter your own equation) and Just select an equation from the extensive In fact, you can usually fitД¬urves in a single step. Often more difficult than it needs to be. Nonlinear regression is an important tool in analyzing data, but is
