DOI: 10.1007/s42952-019-00041-9
Abstract: In some sampling situations, the survey can result in an estimate of zero when it is known that the parameter being estimated is close to, but not equal to, zero. Examples include searching for rare… read more here.

DOI: 10.1021/acsami.2c08511
Abstract: In this article, we report on high-performance deep ultraviolet photodetectors (DUV PDs) fabricated on metal-organic chemical vapor deposition (MOCVD)-grown β-Ga2O3 heteroepitaxy that exhibit stable operation up to 125 °C. The fabricated DUV PDs exhibit self-powered… read more here.

DOI: 10.1080/00949655.2019.1590580
Abstract: Abstract While excess zeros are often thought to cause data over-dispersion (i.e. when the variance exceeds the mean), this implication is not absolute. One should instead consider a flexible class of distributions that can address… read more here.

DOI: 10.1088/1748-9326/acd5e8
Abstract: Agriculture accounts for 12% of global annual greenhouse gas (GHG) emissions (7.1 Gt CO2 equivalent), primarily through non-CO2 emissions, namely methane (54%), nitrous oxide (28%), and carbon dioxide (18%). Thus, agriculture contributes significantly to climate… read more here.

DOI: 10.1093/biomet/asac050
Abstract: Zero-inflated nonnegative outcomes are common in many applications. In this work, motivated by freemium mobile game data, we propose a class of multiplicative structural nested mean models for zero-inflated nonnegative outcomes which flexibly describes the… read more here.

DOI: 10.1111/nyas.14970
Abstract: More than 100 countries have communicated or adopted new Nationally Determined Contributions (NDCs) and net‐zero target pledges. We investigate the impact on global, national, sectoral, and individual greenhouse gas emissions projections under different scenarios based… read more here.

DOI: 10.1155/2021/5874275
Abstract: In healthcare research, medical expenditure data for the elderly are typically semicontinuous and right-skewed, which involve a point mass at zero and may exhibit heteroscedasticity. The problem of a substantial proportion of zero values prevents… read more here.

DOI: 10.3389/fpsyg.2021.583734
Abstract: While knowledge on the development of understanding positive integers is rapidly growing, the development of understanding zero remains not well-understood. Here, we test several components of preschoolers’ understanding of zero: Whether they can use empty… read more here.
