In many applications, the probability density function is subject to experimental errors. In this work the continuos dependence of a class of generalized entropies on the experimental errors is studied. This class includes the C. Shannon, C. Tsallis, A. Rényi and generalized Rényi entropies. By using the connection between Rényi or Tsallis entropies, and the distance in a the Lebesgue functional spaces, we introduce a further extensive generalizations of the Rényi entropy. In this work we suppose that the experimental error is measured by some generalized Lp distance. In line with the methodology normally used for treating the so called ill-posed problems, auxiliary stabilizing conditions are determined, such that small - in the sense of Lp metric - experimental errors provoke small variations of the classical and generalized entropies. These stabilizing conditions are formulated in terms of Lp metric in a class of generalized Lp spaces of functions. Shannon's entropy requires, however, more restrictive stabilizing conditions.
