Following the ground-breaking measurement of the tensor-to-scalar ratio r = 0.20(-0.05)(+0.07) by the BICEP2 collaboration, we perform a statistical analysis of a model that combines Radiative Inflation with Dark Energy (RIDE) based on the M-2 vertical bar Phi vertical bar(2) ln (vertical bar Phi vertical bar(2)/Lambda(2)) potential and compare its predictions to those based on the traditional chaotic inflation M-2 vertical bar Phi vertical bar(2) potential. We find a best-fit value in the RIDE model of r = 0.18 as compared to r = 0.17 in the chaotic model, with the spectral index being n(S) = 0.96 in both models.
