For all respondents included in our analyses, completely observed data were available for patients' HES-recorded age, gender and socioeconomic status (using the Index of Multiple Deprivation score of lower super output area of residence).
"Until yesterday, the company believed the process was working and was completely observed," Kenneth Marks, a lawyer for Enron, said today.
Various approaches have been described to estimate the proportional hazard model in case-cohort surveys: Weighted estimators [ 2- 6] are classically used in these surveys, with analysis restricted to the completely observed subsample, so the information collected for incompletely observed non-cases is ignored and inefficient estimators for the effect of phase-1 variables are obtained.
The results of complete case analyses were very close to the imputed data analyses as expected given that all the outcome variables were completely observed and the missing indicator variables for the incomplete covariates did not have strong relationship with the outcome variables (see online supplementary tables S6 and S7).
For such partially observable systems, it is essential to convert them into completely observed ones, which can be done by using a Wonham filter [22 24].
We included only completely observed days in the analysis.
However, completely different tendencies were observed for the Naïve Bayes algorithm, which in all cases showed only a slight sensitivity to the negative training set size enlargement (Figure 2).
A completely similar trend was observed for thiols anchored on metal nanoclusters as well as metal surfaces, and extensively discussed in the literature [59, 60].
PF of proteases in the top phase was shown to increase with increasing MPEG and decreasing CC, whereas a completely opposite trend was observed for K. On the other hand, Y was favored by simultaneous decreases in both these variables, while S decreased with increasing CC.
It is interesting to note that the response of K in these figures is completely the same as observed for M. It is also found from these figures that momentum boundary layer become thinner in case of β → ∞ and the opposite to this for thermal and concentration boundary layer thicknesses.
