Abstract
Logistic distribution (LogDis) is frequently used in many different applications, such
as logistic regression, logit models, classification, neural networks, physical sciences,
sports modeling, finance and health and disease studies. For instance, the distribution
function of the LogDis has the same functional form as the derivative of the Fermi
function that can be used to set the relative weight of various electron energies in their
contributions to electron transport. The LogDis has wider tails than a normal distri-
bution (NorDis), so it is more consistent with the underlying data and provides better
insight into the likelihood of extreme events. For this reason the United States Chess
Federation has switched its formula for calculating chess ratings from the NorDis to
the LogDis. The outcomes of many real-life experiments are sequences of record-
breaking data sets, where only observations that exceed (or only those that fall below)
the current extreme value are recorded. The practice demonstrated that the widely
used estimators of the scale and location parameters of logistic record values, such as
the best linear unbiased estimators (BLUEs), have some defects. This paper investi-
gates the shrinkage estimators of the location and scale parameters for logistic record
values using prior information about their BLUEs. Theoretical and computational
