Sentence examples for aft estimates from inspiring English sources

Further advantages of this method include the conversion of AFT estimates to hazard ratios and its possible extension to trials in which patients switch in both directions between treatment arms, thus easily enabling inclusion of the results into an economic decision model.

Accelerated failure time models differ from the more established proportional hazards (PH) models in that rather than estimating a baseline hazard function, AFT models instead estimate a baseline survival function.

An Accelerated Failure Time (AFT) model was developed to estimate the driving time before detection of drowsiness.

To facilitate risk stratification and survival prediction, the accelerated failure time (AFT) regression models were used to estimate the acceleration factor of each prognostic predictor and to construct predictive models for survival duration and probability.

AFT spokeswoman Kate Childs Graham provided The Huffington Post with estimates of the union's past spending that are significantly higher: $15.3 million in 2008, $18.6 million in 2010 and $19.5 million in 2012.

Adjusted median latencies were estimated using predicted values from the full AFT model.

To estimate the effect of circumcision on HR-HPV clearance, the Weibull frailty model 4 and log-logistic AFT frailty model 6 were applied respectively, and the model parameters were estimated by maximizing the full likelihood given in equation 7. Table 2 lists the parameter estimates from the Weibull frailty model (left panel) and Log-logistic frailty model (right panel) obtained by PROC NLMIXED.

Quantile–Quantile plots were used to determine the appropriateness of the AFT framework and Akaike's Information Criterion AICC) to select between models estimated using the log-normal, log-logistic, and gamma distributions (Akaike, 1974; Bradburn et al, 2003).

We then utilized the combinations of the resulting individual's subgroup or class membership and class-specific characteristics (level and rate of FSH change at class-specific pre-specified ages) to estimate associations with FMP age under a Bayesian accelerated failure time (AFT) model.

> -wrap-foot> > Maximum likelihood parameter estimates for the eight triplets are shown in figure 2. Speciation appears to be most recent in triplets AFT (= 0.0003 ± 0.00089) and CTO (= 0.0003 ± 0.00004).
