Hi, my question is really precise. I'm interested in drops of stomacal temperature (of seal pups) following milk ingestion. Temperature starts at an average of 37.8oC (sd=0.2) and drops rapidly to around 36.0oC and then stabilizes slowly to a temperature silimar to the previous one. It looks a bit like an inverse skewed bell curve.
I want to find different points on that curve, and I have a hard time trying to code one of them. I want to determine the point after ingestion (after the temperature drop) where the temperatures reaches stability, i.e. where temperature is stable to plus or minus 1 sd for a period of 10 minutes or more. I have data almost every second and I calculated that a 10 minutes period corresponded to an average of 400 lines. Also, I want to determine the area under the curve, i.e. the area enclosed by the inverse skewed curve (which I don't know the equation).
