The perfectly inverted U-shape of the ratio (mathrm{RE}_{mathrm{LIMO},t}) could be explained by two factors: a gap in wages and a gap in hours worked.
With respect to overall survival (cf. Figure 5), approach J restricts too much the shape of the hazard ratio.
This article demonstrates that the shape of the hazard ratio in the "illness-death" model depends on the inclusion or exclusion of time depending covariates.
The CLR is maximized and is significant (P < 0.01) at age-1 in all three populations and in the pooled sample, although the exact position of CLRmax and the shape of the likelihood ratio surface vary between samples.
This explains why the correlation with time has the lowest power here as the other two tests are more robust to the shape of the hazard ratio over time.
When stratifying the analysis by early warm season (May through July) to late warm season (August through September), the shape of the risk ratio response function did not differ significantly (data not shown).
The aim of this article is to propose several methods that allow to investigate how and whether the shape of the hazard ratio after an intermediate event depends on the waiting time to occurrence of this event and/or the sojourn time in this state.
Furthermore, by importing the data into GACK (Genome Analysis by Charles Kim), software built around an algorithm that selects a dynamic cut-off value based on the shape of the signal ratio distribution [ 31], a binary classification of presence/absence could be applied to generate a list of present/absent probes which is represented diagrammatically in Figure 1B.
It should be noted that for QTL identified on chromosomes 20 and 27, the shape of the likelihood ratio test (LRT) curve was the same for all digestive efficiency traits although the LRT did not reach significance for all of them.
In general, the shape of the duration ratios obtained largely differ from those presented in Kottke and Rathje [3], which follows the same shape of the over-prediction ratios (αAF, Fig. 8).
