We know from genetic studies of patients who are heterozygous for loss-of-function mutations in their ANGPTL3 gene that they have half-normal levels of plasma ANGPTL3, and correspondingly, lower levels of plasma triglycerides and cholesterol.
i]; for example, Aigner, Lovell, and Schmidt (1977) assumed half-normal and exponential distributions, Stevenson (1980) assumed a truncated-normal distribution, and Greene (1990) assumed a gamma distribution.

I restricted analyses to those functions that are known to model detection function well (uniform, half-normal, and hazard rate) with cosine, hermite, or simple polynomial adjustments (Thomas et al.
2]; the model Half-normal cosine adjustments order 2 was the lowest Akaike Information Criterion (Table 1) with an effective band width (ESW) of 7.
It looks unpromising at the moment, but in half-normal times you can save money by moving to one that is raising its prices less aggressively.
Most past studies have used the half-normal and truncated normal distribution because of the ease of estimation and interpretation (Kirkley et al.
The following distributional assumptions refer to the half-normal (HN) model (Kumbhakar and Lovell, 2000).
