The use of Gelfoam™ embolization did not prevent significant bleeding in these two patients, possibly because the tracts could not be exactly approximated, or the Gelfoam™ pledget became displaced.
Just approximate a retorty cadence.
When these requirements cannot be satisfied exactly, optimal (approximate) solutions are sought.
Eigentriple grouping aims at arranging the eigentripes in sets in order to separate additive components that are exactly or approximate separable, facilitating the analysis of the eigenvectors.
Queries are run exactly and approximated by unspecifying one, two and all node labels and replacing one edge with an approximate path constrained to less than 3 and 7 edges.
The approach is a computational one in which quantities that are intractable to evaluate exactly are approximated by sample averages from randomized algorithms.
Although the distribution used for simulating the QTL effects and that used for analysing the data did not agree exactly, 'BayesB' approximates the prior distribution of the QTL effects better than the regression methods.
The Fisher's exact test has more power than a chi-square test when there are low expected values, because the significance is measured exactly, not approximated (Agresti, 1992).
The method requires the lowest-eigenvalue eigenvector of the Hessian which can be calculated exactly or approximated by a method such as the dimer method, Lagrange multipliers,or the Lanczos method.
What are the arguments for using this model (other than that it seems to work post factum, e.g., reproduce the linear slope, etc).? This model serves as a basis of approximation, so what exactly is being "approximated" in this approach, i.e., what is disregarded and what is kept?
