Hi Ken
In the learning curve equation why do we take log r/log 2 ?
And what is the reason for using log 2
It’s called Wright’s law and it supposedly works.
Using the formula gives results identical to those obtained from doubling output each time and working out the cumulative average unit curve. However, the formula allows you to fill in the gaps ie output not falling on a doubling point.
i understood it. but i am very curious to know why log 2 ?
No real idea – just the way the maths works and I have never found a derivation. Probably to do with the original formulation which talks of doubling output ie x2.
