BGB is often estimated indirectly, using root-to-shoot ratios (R/S) [17 21], root system biomass expansion factors (BEFs) [17], and by using regression equations of BGB versus aboveground biomass (AGB) [18, 22, 23] or versus easily measured variables (diameter at breast height (DBH) and tree height (TH)) [23, 24].

Six aliquots of both dilutions were processed along with freshly spiked calibration standards and analyzed by back calculation using regression equation obtained.
When such reference articles were not available, we alternatively estimated the midpoints using regression equations created by the multiple Gini centiles reported in the same article.
On the basis of the results, obtained by performing a big number of computer runs, by using regression analysis and interpolation functions, equations for the calculation of tooth deflections and fillet stresses are derived.
To account for clustering, the effect of hospital volume was analyzed by using regression model with generalized estimating equations methods [ 19], specifying an exchangeable structure of a working correlation matrix, to construct regression models.
In addition, the empirical equations of drill bit temperatures were derived by using regression analysis.
Framingham risk score was calculated by using the regression equation from D'Agostino 2008 [ 12].
Hence, from a given value of salivary glucose, we can predict serum glucose level and HbA1c percentage by using the regression equation.
Results were determined by using a regression equation relating trolox concentrations and the net area under the kinetic fluorescein decay curve (y = ax2 + bx + c).
