1. Re: generate a power trendline from observed data
lei.chen.0 May 16, 2018 10:32 PM (in response to William Graham)Hello William,
This is difficult in Tableau.
By using the calculations described in How to Calculate a Linear Regression Line in Tableau (This is a GREAT tutorial!),
the calculation of b and c are possible.
The problem is that, the calculation of b and c is based on x range 26, while the prediction is necessary for the full set of x.
This is as far as I can go.
Let's wait for jumpins.
Regards
Lei
