# Table 19. Estimated Regression Coefficients for Foods as Predictors of Quarter Root fiber (gm) by Sex & Age Group

For grams of fiber, estimation of b0 and b1...b29, the model is:

E ([fiber].25) = b0+ b1NFG1P1 + b2NFG2P2 + ... + b29N FG29P29

For cube root grams of fiber, for each age group and sex, the estimates of the parameters are:
