Table 18. Estimated Regression Coefficients for Foods as Predictors of Square Root of Ounce-Equivalents of Whole Grains by Age Group & Sex

For MyPyramid ounce-equivalents of whole grains, estimation of b0 and b1...b9, the model is:

E ([Whole Grains].50) = b0+ b1NFG1P1 + b2NFG2P2 + ... + b9 NFG9P9

For MyPyramid ounce-equivalents of whole grains, for each age group and sex, the estimates of the parameters are:
