XLfit is a Microsoft Excel add-in that performs regression analysis, curve fitting, and statistical analysis. XLfit generates 2D and 3D graphs and analyzes data sets produced by any type of research. XLfit includes over seventy linear and non-linear curve fitting models. Predefined categories include: * Exponential/Log, Power Series, Sigmoidal, Hyperbolic, Yield Density, Linear, Polynomial, Dose Response, Pharmacology, Equilibrium, Inhibition * Levenberg-Marquardt fitting algorithm A range of statistical calculations is able to be applied to the data from within the spreadsheet. Example statistics include: * F test and T test * Area under the curve * Confidence intervals * Error values relating to parameter values or any point on the curve. Available statistics models includeSpearman's Rank Correlations, Student's T-Test, Mann Whitney U-Test, least squares, ANOVA, among others. It is possible for a user to add their own models and statistics to the provided ones using a model editor. XLfit was validated by The UK National Physical Laboratory in 2004; the unit tests for this are provided in the model editor from version 5.4 onwards to allow each version to be easily validated. XLfit was used by NASA to analyze the battery life of the Curiosity Mars Lander. (en) |
