The pattern statistics are computed (from left to right) through binomial, compound Poisson or large deviations approximations.
As said in introduction, many kind of approximations are available (Gaussian, binomial, compound Poisson or large deviations).
In table 3, we compare the empirical results using binomial approximations (like above) but also compound Poisson or large deviations approximations.
Those terms that were determined to be clearly generic (e.g. organic acid, organoheterocyclic compound) or described large numbers of known compounds were assigned to SuperClasses.
Formation of acetaldehyde by the oxidative dehydrogenation of ethanol depends critically upon the reaction step that requires the oxide surface to acquire a negative charge: when ethanol is injected into the micro-reactor containing either a pure nanofilm compound or a large fraction of ethanol, it was found to be transformed to acetaldehyde.
It has been argued that the explanation lies in an oxygen-free reducing atmosphere in early geological times, under which iron could readily be transported in solution as ferrous compounds to the ocean or large lakes, where deposition eventually took place, perhaps through the agency of primitive organisms.
Most of these compounds bearing polar functionalities or large lipophilic residues did not show appreciable oral bioavailability in rodents while small and less polar analogs displayed moderate to good oral bioavailability.
The standardized canonical SMILES were then filtered for small or large compounds (100 Da < MW < 900 Da) and checked for duplicate ligand structures to ensure only one set of protein ligand pairs were retained.
Parameter (alpha _{text{i}}) can be estimated from the data using peaks that have no decomposition as a sub-formula of the known molecular formula of the compound, or masses larger than the mass of the precursor peak: these peaks are generally noise peaks.
When π is known (and hence μ), several statistical methods are available to compute S: exact computations [ 1- 4], Gaussian [ 5, 6], binomial [ 7, 8], compound Poisson [ 9- 11] or large deviations approximations [ 12].
