Hi,

From the Figure 3.48 Box Cox Y Transformation from JMP webpage

The plot shows that the best values of λ are between 0.1 and 2.0. The value that JMP selects, using interpolation between the best two values in the 0.2-unit grid of λ values, is 1.124.

I would like to know how to interpret this lambda value : 1.124. After interpret, what should I do? will this data transform to normality?
