GraphPad Prism 集生物统计、曲线拟合和科技绘图于一体，其所具有的功能均非常实用和精炼，包括了一些特色的功能，如ROC曲线分析、Bland-Altman分析等；曲线拟合功能是GraphPad Prism超越其他统计软体的制胜法宝，GraphPad Prism的线性/非线性拟合功能使用操作极其方便，不仅内置了常见的回归模型，还专门内置了Aadvanced Rradioligand Bbinding, Bacterial Growth, 剂量反映曲线，峰拟合等数十个生物统计模组，GraphPad Prism的绘图功能也很具特色，无需专门绘製统计图形，只要输入资料，图表自动生成且随资料改变及时更新，非常方便实用。
能进行自定义方程曲线拟合的软体中，GraphPad Prism的操作最为简便快捷，拟合前参数设置方便，拟合速度快，并支援批量拟合，这在同类软体中非常少见，可以说GraphPad Prism当之无愧为非线性拟合的高手。
Prism 在科学图表的绘制方面可以视为Sigmaplot的替代软体，但是却又包含了简单的试算表，可以直接输入原始数据，软体自动计算标准差和p value，此外，也包含了其他几项数值分析的能力。
GraphPad Prism 7.0a
Utility for biostatistics, curve fitting and scientific graphing. GraphPad Prism is a powerful software solution for managing and organizing scientific data gathered during different experiments. The GraphPad Prism application provides the necessary tools for creating scientific graphs, can generate relevant statistics and much more.
GraphPad Prism was originally designed for experimental biologists in medical schools and drug companies, especially those in pharmacology and physiology. Prism is now used much more broadly by all kinds of biologists, as well as social and physical scientists. More than 200,000 scientists in over 110 countries rely on Prism to analyze, graph and present their scientific data. It is also widely used by undergraduate and graduate students.
Moreover, GraphPad Prism provides support for working with nonlinear regressions for analyzing data and usually reduces curve fitting to a single step.
Also, GraphPad Prism allows you to use your data in t tests, one- and two-way ANOVA, nonparametric comparisons, contingency tables and survival analysis. GraphPad Prism is not only a tool for analyzing data sets: it is able to efficiently record all the steps included in your experiments.
What’s new in Prism 7?
– Heat maps
– Three-way ANOVA
– FDR approach to multiple comparisons
– More accurate (asymmetrical, likelihood) confidence intervals from nonlinear regression
– Label sub-columns
– Color code sheet names, and selected cells in tables
– Semitransparent colors so you can see overlap
– Enter dates (or elapsed times) as X values
