This post is following of above post.
Let's see which year has many observations.
Okay, 2014, 2010, 2006 and 2018 have over 20 observations.
Let's see those years more.
First, emp density
Second, self density.
Third, emp vs. self.
Let's check if there is significant correlation between emp and self.
p-value is 0.3947, correlation is 0.08271758.
So, there is not significant correlation between emp and self.
That's it. Thank you!
