We discuss the application of an analytic approach called the analytic perturbation theory (APT) to the QCD analysis of DIS data. In particular, the results of the QCD analysis of a set of `fake' data on the polarized nonsinglet Deltaq3 and the nonsinglet fragmentation function Dpi+ᵤᵥ by using the Q²-evolution within the APT are considered. The `fake' data are constructed based on parametrization of the polarized PDF and nonsinglet combination of the pion fragmentation functions. We confirm that APT can be successfully applied to QCD analysis of Deltaq₃(x,Q²) and Dpi+ᵤᵥ(z,Q²) and that the inequality LambdaAPT > LambdaPT obtained previously for the xF3(x) structure function takes place.
