Table 1.

Estimated coefficients (“Beta”) and p-values from two analysis strategies. Multiple linear regression (MLR) results are shown in the first columns; function-on-scalar regression (FoSR) results are shown in the second columns. For the FoSR model, estimated effects are the integrated coefficient functions and p-values are global tests of significance for the coefficient function.
