I tried to do “Fit life by X” (fit TTF by voltage), but in the output, somehow “nonparametric overlay” did not show up. I was hoping to see the probability of failure vs time at 80V, 50V, and 15V (use condition), but that plot was not included in the output. I attached the report here. If anyone can take a look and point out went wrong, that would be great. Thank you!
