I'm going into University this year, Engineering to be more specific and I was given an assignment over the summer about regression. (Something I have no knowledge about) Basically, in my questions I have two questions that I have no idea about answering. Here they are...
I need to describe the significance of the intercept. In my thing on excel I have a few different kinds from what I can see. Theres an image attached so you can see. I have things like "Coefficient, t Stat, P-value..." Whats the significance of the intercept? For this assignment its basically about finding the Total Energy, Total Charge, Power, and I^2 (By the way, what would you call I^2?) from the elapsed time, Voltage, and Current in a series circuit. I highlighted in blue the intercept and standard error in the image
This one is hard, I cannot find anything to help me...What should the intercept be if there are no measurement errors?
Please any help will be appreciated!
