Quantification of hyperspectral downwelling vertical attenuation coefficient (Kd) and irradiance (Ed) in the euphotic depth (Zeu) in 2005 (falling) and 2006 (rising waters) in Amazonian waters showed that Kd is higher in the blue (5-9 m), decreasing towards the green (4-7 m) and red (3-5 m) part of the spectra. Further, Kds are generally higher in white waters than in black and clear waters. A ...

Given data y and k covariates x one problem in linear regression is to decide which in any of the covariates to include when regressing y on the x. If k is small it is possible to evaluate each subset of the x. If however k is large then some other procedure must be use. Stepwise regression and the lasso are two such procedures but they both assume a linear model with error term. A different ap...

Nelson and Sprecher used such methodology to identify various national attributes that correlate to states peaceful use of nuclear power for electricity generation, which was termed as “Nuclear Reliance.” The major init...

The study on soil spectral reflectance features is the physical basis for soil remote sensing. Soil organic matter content influences the soil spectral reflectance dramatically. This paper studied the spectral curves between 400nm~2500nm of 174 soil samples which were collected in Hengshan county and Yixing county. Fourteen types of transformation were applied to the soil reflectance R to remov...
