Hello all. I'd like to find a basic formula for an S curve calc in
excel. Variables would be equal to Y = moeny vs. X time (or period).
Ymax would be the budgeted cost of the project, and Xmax would be the
budgeted time for the project.
current calculation I'm using is:
Y = Ymax ((2(X/Xmax)^2) - (X/Xmax)^4)
While this does give me a curve, I need a curvier curve.
help would be appreciated.
