I need to plot a kernel density for attached data but I dont know how to do it.Read some material online and watched tutorials on youtube but coudn't wrapped my head arround the plot.

Would highly appreciate if someone can help me with that.

I am attaching my data.

Hi,

It is similar to the normal distribution curve.I have attached an example.

I think normall distribution curve is also one of the kinds of kernel density function but am not sure about that.

I found a script for estimating Kernal density on MATLAB file exchange:

It should be able to work on your data, so give it a try.

在 MATLAB Online 中打开

You also can use ksdensity from the Stats toolbox. But you have supplied us with a matrix with 25 columns! Which column were you intersted in? (Presumably you are in 1D).

load ChangeinBeta
A = ChangeInBeta;
ksdensity(A(:,1)) % just do 1st column
