Python中的fitter包能有效完成数据分布拟合任务。首先，通过一个实例展示其使用方法。简单代码即能输出最优拟合分布及误差，并展示数据分布与拟合分布图像。随后，详细介绍Fitter类及其参数，关键在于如何声明Fitter实例，利用参数列表进行拟合操作。使用f.fit()方法进行拟合，随后调用相关方法如绘图、获取误差、...
print(pt.fit(data)) print('\n参数λ=',pt.lambdas_) print('\n拟合后的数据\n',pt.transform(data)) #Fit to data, then transform it. 1. 2. 3. 4. 5. 6. 7. 5.2.3、 两种方法的对比结果: 5.2.4、强调了在幂变换前后对数据进行可视化的重要性 发现有时候幂变换不一定有效。应用到某些分布...

Introduction / 引言 大学期间用来打发无聊时间学的Python没想到竟然在写毕业论文的时候用处这么大,整个硕士论文所做研究,从前期的数据整理、数据分析,到最后的数据可视化我基本上都使用Python来完成,这篇博客就来分享下我毕业论文课题中所做数据分析相关的Python代码。 本博文所有相关的代码都上传在GitHub仓库:Data-Analys...
