At fixed virtuality Q^2, as we showed previously, our expression is an expansion in powers of log (1/x) that satisfies the Froissart bound. Here we show that for each x, the Q^2 dependence of the data is well described by an expansion in powers of log Q^2. The resulting analytic expression allows us to predict the logarithmic derivatives {({\\partial}^n F_2^p/{{(\\partial\\ln Q^2}})^n)}_x for n = 1,2 and to compare the results successfully with other data.
