Table 14. Estimated Regression Coefficients for Foods as Predictors of Quarter Root Fiber (g) by Sex

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

E ([Fiber].25) = b0+ b1NFG1P1 + b2NFG2P2 + ... + b9N FG29P29

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