2nd Class, obs SEQUENCE
3rd Nutrient KCAL
10th Class, obs DOW
11th Weight INDWT
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
Maximum number of join points allowed: 12

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