This toolbox provides functions and graphical user interfaces for analyzing historical data , modeling data , simulating systems , and developing statistical algorithms . This establishes the need to compare the temporal evolution and spatial pattern of model relationships with the corresponding covariability in observed and measured climate variables on decadal time scales . Despite its abstract form , it 's an application that has many real-world purposes , such as modeling data or comparing rates of change . The model scenarios used in HERS and NBIAS to construct the " Improve " and " Maintain " scenarios are discussed in greater detail below . Since some findings from both experiments were consistent with each other , modeling assumptions , such as a second-order kinetic relationship for Cu dissolution ( by H2SO4 ) and a first-order equilibrium isotherm for Cu , were appropriate in order to simulate the Cu recovery concentration at the outlet of each column . This model views drug abuse and chemical addiction in some instances as attempts by the individual to self-medicate overwhelming affect in the absence of alternative coping mechanisms .
