XLfit is a Microsoft Excel-based plug-in which allows curve fitting and statistical analysis. XLfit generates 2D and 3D graphs and analyses data sets produced by any type of research. XLfit’s curve fitting engine allows linear and non-linear curve fits, smoothing, statistics, weighting and error bars. 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 can also 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 include Spearman's Rank Correlations, Student's T-Test, Mann Whitney U-Test, Sum of Squares, ANOVA, among others. XLfit 4 was validated by The UK National Physical Laboratory〔http://www.engineeringtalk.com/news/ade/ade261.html〕 in 2004 == Version History == * 2002.8 XLfit 2.0.11 * 2002.5 XLfit 3.0.2 * 2003.11 XLfit 4.0.1 〔http://www.drugdevelopment-technology.com/downloads/whitepapers/bioinformatics/file225/ Drug Development and Technology - XLfit and John Deere〕〔Scientific Computing & Instrumentation, Monday, March 1, 2004〕 * 2005.6 XLfit 4.1.1 * 2005.6 XLfit 4.2.0 * 2008.7 XLfit 4.3.2 * 2009.4 XLfit 5.1.0 * 2009.7 XLfit 5.1.1 * 2009.11 XLfit 5.2.0 * 2010.11 XLfit 5.2.2 * 2011.11 XLfit 5.3.0 * 2012.1 XLfit 5.3.1 * 2014.5 XLfit 5.4.0 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「XLfit」の詳細全文を読む スポンサード リンク
