On the Kumaraswamy-Dagum-Log-Logistic sigmoid functions with applications to population dynamics
he Kumaraswamy-Dagum distribution is a flexible and simple model with applications to income and lifetime data.
We prove upper and lower estimates for the Hausdorff approximation of the shifted Heaviside function by a class of Kumaraswamy-Dagum-Log-Logistic cumulative distribution function - (KD-CDF). Numerical examples, illustrating our results are given.
