Sentence examples similar to time dependent birth from inspiring English sources

The time-dependent birth-death model assumes a molecular clock that starts ticking for all duplicates at the root.

Similar results about biases and parameter estimates under constant and time-dependent birth-death processes have been obtained in [ 57].

Since each mechanism has a unique density curve, this result indicates that it is possible to distinguish three mechanisms using the time-dependent birth-death model.

Nevertheless, these results suggest that maximum likelihood methods can accurately estimate parameters in the time-dependent birth-death model when the sample size is large.

Thus, in the time-dependent birth-death model, the loss rate μ t of a gene copy is a function of time t.

In this section, the time-dependent birth-death process is extended to the age-dependent process, where the clock for each duplicate starts ticking at its birth.

The time-dependent birth-death model described in the previous section starts with a single population corresponding to the lineage of a phylogenetic tree and assumes a molecular clock that starts ticking for all duplicates at the root.

To evaluate the performance of the time-dependent birth-death model on simulated data where the true values of parameters are known, we generated duplication times of gene copies using the rejection-sampling algorithm with the conditional probability density function of duplication times in Eq. (3).

Starting with a single population corresponding to the lineage of a phylogenetic tree and with an assumption of a clock that starts ticking for each duplicate at its birth, an age-dependent birth-death process is developed by extending the results from the time-dependent birth-death process.

The solution should be of sufficient generality to capture the rates of coalescence between all pairs of branches as a function of time-dependent births, migrations, and population size.

Further studies are needed to elucidate the mechanisms for these time dependent patterns of preterm birth for migrants.
