In this study, we define a generalized hyperbolic secant distribution. Poor
fit to heavy tailed data sets is repeatedly obtained by existing
three-parameter distributions. Only three parameters are considered in the
proposed new distribution and it fits a heavy left- and right-tailed data
better than various existing distributions. We study some properties of the
new distribution, namely, mode, skewness, kurtosis, hazard function,
moments, mean deviation, and Shannon entropy. Seven different frequentist
methods for estimating the parameters are briefly described. A simulation
study is also conducted to compare the performances of the proposed methods
of estimation. The usefulness of the new model is demonstrated by applying
it to fit two real-life data.
