Confidence Intervals for the Difference and Ratio of Two Variances of Delta–Inverse Gaussian Distributions

Accurate statistical inference for zero-inflated and highly skewed data requires confidence interval procedures with a strong finite-sample performance. The delta–inverse Gaussian distribution provides a flexible framework for modeling such data by combining a point mass at zero with an inverse Gaus...
