Histogram and Density Plotantoine Filipovic Pierucci
此时,图像反映的是其概率密度,直方图的面积总和为1。 除了频次直方图,我们还可以用KDE(kernel density estimation)获取变量分布的平滑估计。具体请见下一篇:Matplotlib学习---用seaborn画直方图/核密度图(histogram, kdeplot)。
histogram绘制条件直方图,densityplot绘制条件核密度图。默认面板函数使用density函数来计算密度估计,并且density接受的所有参数都可以在对densityplot的调用中指定以控制输出。有关详细信息,请参阅density的文档。 这些和所有其他高级网格函数有几个共同的参数。这些仅在xyplot的帮助页面中进行了大量记录,应查阅该页面以了解更...

We’ll make a histogram and density plot for Beaver #2, wrap the graphs in a layout and png, and change the x-axis to be the same, using xlim. Here’s the final code, also available on gist: png("beaverhist.png") layout(matrix(c(1:2), 2, 1, byrow = TRUE)) hist(beaver1...

The binwidth is proportional to the interquartile range (IQR) and inversely proportional to cube root of a.size. Can be too conservative for small datasets, but is quite good for large datasets. The IQR is very robust to outliers.
