Hi all, Does anyone know the original applications or the "meaning" of the "S"-function in SPSS? I know the function itself: Y = e**(b0 + (b1/t)) or ln(Y) = b0 + (b1/t) and I know how the curve looks like, but I am wondering in which fields of research this function is typically used and which empirical relations it describes? Thanks for any hint, Johannes
