Fig. 3From: Estimating the size of urban populations using Landsat images: a case study of Bo, Sierra Leone, West AfricaBack-transformed estimators of the \(ln(d_i)\) and \(\sqrt{d_i}\) of the population density \(d_i\). (a) No transform (b) back-transform of \(\widehat{ln{(d_i)}}=e^{\widehat{ln(d_i)}}\) (c) back-transform of \(\widehat{\sqrt{d_i}}={[\widehat{\sqrt{d_i}}}]^2\)Back to article page
