I graduated 3 years ago and defendeded my master's thesis without any problem. Since recently, I am planning to go back to academia, so my former advisor and I are working together to publish my master's project.
While doing so, I've recognized coding mistakes that affect results statistics. Thankfully, it does not change the whole implication and main findings but it changes some statistics numbers and minor results (which are not essential to the research hypothesis).
I don't know what to do. It was a mistake that I did not recognize at that time. I cried over and over for two days, and could not sleep soundly due to nightmares. I am panicking.
I've heard that I cannot make errata for my master thesis. (I don't know the reason why) What should I do?
