Hey, im doing data management for a engineering lab, and one of the questions asks to prove that doing the semi-log plot of a graph with exponential correlation give the same relation. A semi-log graph is taking all the y values of the exponential graph and applying the natural logirthm to it.
ex: y= 6 in the semi long graph y= ln 6
This will give a linear relationship which is easier to work with.
My question is, they ask me to prove this, by taking the regression equation algebraically alter it to equal thre regression equation of the linear relation ship
this isthe exponential relation:
What exactly does the E mean, and how can i manipulate this to equal,
0.1165x – 229.96
heh back for a bit more help...
so this is what i tried:
=ln (-230) + ln e^(0.2682x)
=ln (-230) + 0.2682x
almost got it! but im not sure what im doing wrong :S
0.1165x – 229.96 is what im trying to get
