  Variable used to determine sample day:              SEQUENCE
  Variable used to tie observations to individuals:   INDIV
  Fraction of mean used to adjust for zero values:    0.0001
  Minimum power tested for best transformation:       1 / 10

============================================================

Nutrient KCAL (weighted by INDWT).

PRELIMINARY ADJUSTMENTS
  Transformation is power of 1 / 2, scale factor of 10e1.
  The maximum number of observations per individual is 4.

  Ratio adjustment variables are:
       DOW, and SEQUENCE.

  Data are adjusted to Day 1 variance after ratio adjustment
  and in transformed scale.  Original scale standard
  deviations of adjusted data for each sample day are:
          Day 1      729.191
          Day 2      782.004
          Day 3      756.602
          Day 4      854.61
