Yes, regression does give you an approximation. AANNnnnndddd, the indication on the indicator is also an approximation. If the system were linear, then a linear regression test would find a line that fit the data. Based on what I've seen, you could, maybe even should, subtract 0.5°C from the calculated value. Regression will find how much change in a binary/hexadecimal/whatever kind of number is needed to make the indicated number change.
In the case of my device. It appears that my system for the most part linear. Linear Regression, in this case, as long as I use the correct pulses and spaces, proves to be quite accurate and precise. Why???? The calculated and floored offset remains parallel throughout time, change in temperature, and temperature. Accuracy could be considered questionable, but even then " I know it's offset".
Regression can be used for accuracy and precision. I don't think one should be so closed minded.
I don't like being an asshole, but you shouldn't have been a closed minded idiot. I may get banned from this site, so what! I only brought an idea that works, with a little bit of hacker spirit. If my idea sucks, bring a better one. You sound like a damn kid, "You did it wrong!" or maybe an old person "Right tool for the right job". And I hope you realize that if you're on the upper end of the age issue, those are typically the people that have to have everything like it used to be, and we may as well be using Wash Boards instead of Washing Machines. If you don't try anything different, regardless of "what The Professor said", or "Dad said", you will never grow. And you become a sheep an ant?, or a bee? ... whatever. Your method of thinking isn't why Hard-drives, CDs, .......
Maybe you already get my point
