The use of regression interval mapping and maximum likelihood methods for QTL detection provided consistent results in many cases, although the high variation observed for traits mean among families made it difficult to evaluate QTL effects.
The degree of variation observed in humans means that our small sample set included individuals with only half the mean value of PHM or PAL, a potentially significant decrease.
As shown in Table 4, the mean intraexperimental precision was 16.2% CV, and the mean interexperimental precision was 15.1% CV in agreement with the variation observed for those of reference standard concentrations.
The variation observed at each time point was <4.7% of the mean value (0.09-5.1).
This means that genetic differences among maternal plants could explain most of the variation observed.
Using experimental measures of the mean and variation of five key proteins in the model, simulation results closely match the time-to-death variation observed.
The mean subject random intercepts, b0 i, are assumed to be normally distributed about the overall mean intercept of the data set, β0, with a variance σ A, which quantifies the amount of between-individual variation observed.
The temporal variation observed in microbial populations could represent either microbial succession, as newly colonizing microbes displaced other species, or stochastic fluctuations about a fairly constant mean.
It is important to realize, however, that the gap observed in any given country is an aggregate that can be represented as a mean estimate of variations observed within regions and health districts.
