Basicity, estimation factors affecting

The art of experimental design is made richer by a knowledge of how the placement of experiments in factor space affects the quality of information in the fitted model. The basic concepts underlying this interaction between experimental design and information quality were introduced in Chapters 7 and 8. Several examples showed the effect of the location of one experiment (in an otherwise fixed design) on the variance and co-variance of parameter estimates in simple single-factor models. 

Prior to determining the carbon in phytomass it is necessary to determine the total biomass. Forest biomass is a basic factor in studies related to nutrient cycling and carbon release from terrestrial systems following deforestation. This is now one of the more important global research themes due to concerns about possible human-driven climatic changes. Biomass estimates have an enormous influence in modeling based on emissions of carbon from deforestation. The use of inaccurate values for this parameter will drastically affect the reliability of the results of the models. 

The pAVvalues can therefore be used to estimate the nucleophilicity of atoms within the same row. It is not exact because the nucleophilicity is strongly affected by steric factors (see Section 4.4), while, the basicity is not.
