Numbers of viral genomes in samples by RT-PCR (PCR-detectable units [PDUs]) were estimated as most probable numbers as described (27 ).
AIC is defined as begin{aligned} mathrm{AIC}=-2log p varvec{Y}|tilde{theta },M +2K end{aligned} (7 where M is the target model, (varvec{Y}) is the observed data, (tilde{theta }) are estimated as the most probable parameters for the target model M, and K is the number of input variables.
Empirical P-values for each test were estimated as the proportion of replicates that is as probable or less probable than the observed data, as implemented in the software package Genetic Data Analysis GDAA).
The time from admission to reclassification as a probable case is estimated as 1/γ; time from admission to removal from suspected SARS case list is 1/α; time for classification as a probable case to death is 1/ρ multiplied by 0.15, the overall case-fatality rate of SARS patients, as estimated by WHO; the time from probable case to discharge is 1/α multiplied by 0.85, the cure rate.
Most probable insertion and deletions of genomic regions were estimated as done previously [ 44], using a maximum parsimony approach.
The attack rate for probable SARS among healthcare workers in Beijing is estimated as 465 per 100,000.
The tree topology estimated as Tree-6 by [ 34] is used here as the most probable one.
The probable maximum precipitation (PMP) for stations in Malaysia using Hershfield formula is routinely estimated as mean plus 15 standard deviations processed from yearly maximum rainfall values.
Dr. Trever, a younger, less experienced man, was not able at once to estimate, as Professor Sukenik had done, the probable age of the manuscripts, but when he began to suspect what they were, he too became much excited.
These age points are used as probable intervention points in order to estimate the present value of potential benefits of prevention activities.
