Hi all, first time poster here, and I have not seen this problem on these boards and hoping for some help.
I am on 18.1.1 and transforming via SHASHTrans and then back using SHASHInv does not return the same value.
Using SHASHTrans with parameters γ -4.73, δ 2.74, θ 345.80, σ 12.87, 400 returns ~1.4. Back-transformation using SHASHInv and the same parameters returns 323.6
Where am I going wrong?!
