'SOHPIE' (pronounced as SOFIE) is a novel pseudo-value regression approach for differential co-abundance network analysis of microbiome data, which can include additional clinical covariate in the model. The full methodological details can be found in Ahn S and Datta S (2023) <arXiv:2303.13702v1>.

Sparsity Oriented Importance Learning (SOIL) provides a new variable importance measure for high dimensional linear regression and logistic regression from a sparse penalization perspective, by taking into account the variable selection uncertainty via the use of a sensible model weighting. The package is an implementation of Ye, C., Yang, Y., and Yang, Y. (2017+).

Soil health assessment builds information to improve decision in
    soil management. It facilitates assessment of soil conditions for crop suitability [such as those given by FAO
    <https://www.fao.org/land-water/databases-and-software/crop-information/en/>], 
    groundwater recharge, fertility, erosion, salinization [<doi:10.1002/ldr.4211>], 
    carbon sequestration, irrigation potential, and status of soil resources.

Facilitates basic and equation-based analyses of some important soil properties related to soil chemical environment and nutrient availability to plants.

Includes four functions: RFactor_calc(), RFactor_est(), KFactor() and SoilLoss(). The rainfall erosivity factors can be calculated or estimated, and soil erodibility will be estimated by the equation extracted from the monograph. Soil loss will be estimated by the product of five factors (rainfall erosivity, soil erodibility, length and steepness slope, cover-management factor and support practice factor. In the future, additional functions can be included. This efforts to advance research in soil and water conservation, with fast and accurate results.
