The command for statistical calculations in graphs is as follows:

Graph bar A B, over (Tag)

The result of this command will look like a following graph:

The command for this is as follows:

graph hbar A B, over(tag)

The output of this command will look like a following graph:

You can also perform median-related calculations and plot the medians accordingly. Here is the code to achieve this:

graph hbar (median) A B, over(Tag)

The following is the output you get after performing median calculations:

We can perform and create the independent kernel density plot by leveraging the kdensity code:

kdensity A

The output of this command will look like the following graph:

Kernel density estimation, which is also known as KDE, is a nonparametric tool that's used to plot the graphs of a selected variable. This is also part of a data-smoothing exercise and is heavily used in economics, signal processing, and the consumer packaged goods (CPG) industry in order to find various...
