Modeling Conditional Skewness in Stock Returns [PDF]
In this paper we propose a new GARCH-in-Mean (GARCH-M) model allowing for conditional skewness. The model is based on the so-called z distribution capable of modeling moderate skewness and kurtosis typically encountered in stock return series.

The Law of the Minimum and Sources of Nonzero Skewness for Crop Yield Distributions [PDF]
Crop yields are not commonly found to be normally distributed, but the cause of the non-normal distribution is unclear. The non-normality might be due to weather variables and/or an underlying von Liebig law of the minimum (LoM) production function.

Research and evaluation of ruts in the asphalt pavement on Lithuanian highways
Journal of Civil Engineering and Management, 2013 When exposed to destructive climate and weather factors and heavy vehicle loads, the pavement wears and deflects. In recent decades, apart from cracks and potholes, the depth of ruts grows and makes an increasing share of the pavement surface. The deeper
