Under the clock dating
Widths of posterior intervals were also very dependent on the position of the calibrated node within the tree, particularly when sequences were short.
This typically occurred when the 95% prior interval did not include the true age and/or sequence lengths were ≤ 1 kbp.A birth-death process with species sampling is used to specify a prior for divergence times, which allows easy assessment of the effects of that prior on posterior time estimates.We propose a new approach for specifying calibration points on the phylogeny, which allows the use of arbitrary and flexible statistical distributions to describe uncertainties in fossil dates.Little is known about their reliability for shallow phylogenies where DNA sequence divergence is low.We analyzed both simulated and real sequences to evaluate dating methods in phylogenies with mid–late Miocene roots.These prices would be reflective of a typical Atmos clock - such as a model/caliber 519, 526, 528 and/or 540 and with the standard brass, gold plated case.
Atmos clocks with Oriental Motif Cases (white or black plexi-glass), the Gruen wood case models or any other models with rare and unique cases will obviously be worth more then the types described above, depending on their condition.
In particular, we use soft bounds, so that the probability that the true divergence time is outside the bounds is small but nonzero.
A strict molecular clock is assumed in the current implementation, although this assumption may be relaxed.
- Clock runs perfectly; case is in perfect condition, no fading and no highline scratches-even at very close inspection; often original box, packing material and documentation included.
A good way of determining the approximate value of your particular clock is to regularly visit on-line Auction Sites; look for clocks at auctions similar to yours, comparing your clock to identical ones with the final "winning bid amounts".
