In short, this is achieved by including a patient-specific random effect factor, γ (the frailty), into the model, and by evaluating hazard rates conditional on this factor.
This is conditional on the following factors: Wage at the job w i (t), the primary variable of interest; A vector of other observable time-varying characteristics of the worker x i (t); A vector of time-varying characteristics of the firm at the time of job spell z j i)(t); and A term for either unobserved individual or firm heterogeneity v i,j i).
When we reanalysed our data using the same comparisons as were previously reported, our crude results, which were conditional on the matching factors (age, sex, general practice, and index date), were consistent with those reported in previous publications.
We evaluated regression models including (1) only the main exposure variables conditional on the matching factors; (2) also smoking, body mass index, and average visit frequency; and (3) the exposure variables and whichever potential confounders were significantly associated with each cancer.
Participants views indicated that being able to succeed in achieving network objectives and therefore achieving both process and hard outcomes is partly conditional on the right factors being in place in order to establish a solid foundation for networks to design evidence-based projects.
In view of these results and acknowledging an adequate item-factor specification as conveyed by the interim E/CFA, a bifactor model was fitted to examine the existence of a general factor, yet still accounting for (conditional on) the three specific factors (Table 1, Model D).
We earlier noted a qualified softening of the position of the OECD inter alia against extension agreements conditional on such factors as the representativeness of the social partners and the dispersion of productivity between firms.
An instructor should be explicit in linking biological phenomena to the concept that the process and quantity of transcription and translation are conditional on the presence of transcription factors and environmental cues.
The ROC_AUCs were 0.817 for the study data set under the conditional logistic regression analysis conditioned on the matching factors.
Finally, a case-control study was utilized for our study, and so a conditional logistic regression analysis, conditioned on the matching factors (i.e., gender, age, and smoking status), was performed in order to evaluate the association between the combination of amino acids obtained above and NSCLC.
The complexity of Verticillium resistance in A. thaliana was particularly striking for stunting resistance, which was highly conditional on environmental factors in the present study.
