Correlation techniques
Basic data wrangling and saving outputs
Inverse Distance Weighting Interpolation of Terrain Attributes, derived from digital elevation model, of Cook Agronomy Farm, Pullman WA
Linear mixed model in agricultural research
Modeling soil pH of Cook Agronomy Farm using RandomForest and Gradient Boosting, probing with partial dependency plots, and selecting the best performing model
Fixed and mixed model comparison, creating graphs with error bar in ggplot, arranging multiple graphs in a grid
Base saturation percentage determination using shrinkage method. Due to the multicollinearity issue, we chose shrinkage/penalized/regularized regression. Since, we have small number of samples, we had no luxury of having separate test set of data, so we did iterated k-Fold cross validation.
