How to change the measured curve to be close to the target curve I am new to Signal processing and want to implement for the measured curve from my experiment.
I have a measured curve (like skewed gaussian).
I like to change that measured curve to be as close as possible to the target curve (gaussian) (statistically and visually). Visually means, the target curve's width is abit longer than the measured curve when we the two curves are overlapped. Which signal processing should I use?
I like to attach a picture, but it is not allowed for the new person.
Thanks

It is unclear what is your application from your question.

If you aim at "gaussianizing" your data -- for example to make better use of statistical modeling, regression, or machine learning methods which work better under a gaussian assumption -- you can use the Box-Cox transform. It consist in applying the following transformation to your data:

$$y = \frac{x^\lambda - 1}{\lambda}$$

$\lambda$ is chosen as to maximize the log-likelihood of a gaussian model given the transformed data - this is a maximization problem usually solved using Levenberg–Marquardt.

I would also strongly suggest posting this to the stats SE.
