The files are organized according to method, with each file
   including all simulation objects pertaining to that method.
   The naming convention used for the objects is as follows:

        "mod" N "d" "Meth" "n"

   where:

  "mod"  = simulation model, with possible values:
           - fl = flat
           - lg = logistic
           - ub = umbrella
           - lb = linear 
           - em = emax
           - se = sigmoid emax

  "d"    = number of doses, with possible values: 5, 7, and 9

  "Meth" = statistical method, with possible values:
           - A  = ANOVA
           - D3 = Dopt (with 2 interim analysis points)
           - Gf = GADA
           - M  = MCP-Mod
           - T  = MTT (multiple trend test)
           - B  = BMA
           - NQ = LOCFIT (with quadratic polynomials)

  "n"    = sample size type: 1 = 250, 2 = 150

  For example, emN7Gf1 names the object with the simulation results
  for GADA applied to the emax model with 7 doses and 250 patients
  total sample size. 

  Each of the simulation objects contais exactly 11 columns with names:
 "DR" = indicator of whether dose response was detected
 "SELDOSE" " = dose selected for Phase III (can be NA)
  "RESP1", ..., "RESP9"  = estimated dose response at doses 0, 1, 
  ..., 8. Can be NA for some methods (when SELDOSE = NA). 
  The order of the columns may vary with method, but not the names.
