We shall therefore approximate the conditional expectation π g, s (t) by the ratio of the expectations (3) This approximation is appropriate and justified for practical purpose because the number of cells at time 0 in CFSE-labeling experiments is typically very large (N0 ≫ 105 or 10).
From 2004, it can be seen that the relation between and mainly depends on three factors (corresponding to the three sources of bias): the effect of the missing covariate, ; censoring mechanism,, and ; and the ratio of conditional expectations,.
To this end, the following approximations were made: expectations of ratios and products were replaced by ratios and products of expectations.
In this case the expected values are nk/ k+1) and n/ k+1), respectively (Note that if k = 1, we have an expected ratio of 1∶1, leading both expectations to equal n/2 and the special case described above).
They avoid the expenses associated with work and dependent children, have mostly paid off the mortgage on their house and no longer need to save for their retirement.But the ratio often falls short of expectations.
However, age- and gender-adjusted odds ratios for complete fulfilment of expectations yielded no significant differences between CAM and COM patients (OR certified CAM: 1.00, noncertified CAM: 1.01), although age appeared as a significant factor.
The stock trades for an expensive price-to-earnings ratio of 91.4, but analyst expectations of 30% annual growth over the next five years might have something to do with that.
In one case of a hepatic metastasis, the T/B ratio of 1.34 was below expectations, since the preoperative [F]FDG PET scan was positive.
The RFF values for Quetzalcoatlus northropi, calculated at three different possible body masses (180 kg, 200 kg, and 250 kg; Table 2) and were always found to have RFF more than twice the expected value for a bird scaled to the same size; in the case of the 180 kg reconstruction, the RFF approaches triple the avian expectation (ratio of 2.82).
