Generate 5,000 normally distributed random numbers with a mean of 5 and a standard deviation of 2. Plot a histogram with Normalization set to 'pdf' to produce an estimation of the probability density function. Get x = 2*randn(5000,1) + 5; histogram(x,'Normalization','pdf') In this ...
plt.show() 图像如下: 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)。
The following histogram in R displays the height as an examination on x-axis and density is plotted on the y-axis. Output: Conclusion That’s all about the histogram and precisely histogram is the easiest way to understand the data. As we have seen with a histogram, we could draw single...
