We report an analysis of the dielectric glasslike state of the spin- and charge-ordered system Lu$$_{2}$$Fe$$_{3}$$O$$_{7}$$, which has structural and physical properties analogous to those of the electronic ferroelectrics ${it R}$Fe$$_{2}$$O$$_{4}$$ (${it R}$: rare earth). Aging and memory effects of resistivity were found in the electric impedance response. We performed a numerical analysis with equivalent electric circuits that have a logarithmic Gaussian distribution of resistance and capacitance. The distribution parameters well explained the glassy nature of the electric and dielectric properties between 100 and 200 K and the distribution variations of charge- and magnetic-ordered domains underlying the glass nature.
