We use our posterior distributions to evaluate the power of several tests that have been used to test the null hypothesis of time-invariance of autoregressive coefficients of VARs against the alternative of time-varying coefficients.
This test favors the auto-correlated rate model alternative while the optimal choice of time prior is found to be more data dependent.
There's navigation of a different sort in The Indivisible Present (Modern Art Oxford, 6 Feb to 16 Apr), which tracks how artists – Douglas Gordon, Pierre Huyghe and Elizabeth Price among them – have attempted to evoke a non-lineal, alternative sense of time in their work.
5 It is straightforward to allow for alternative uses of time suchas market work.
Task variables are associated with the nature of the decision itself, for instance, the uncertainty involved in each alternative, pressure of time and available money, quantity and quality of the information, proposed goals, and possible consequences of the decision.
In light of the frame format of the MP3 bit stream, one granule corresponds to about 13 ms, which means that it is indeed an alternative representation of time.
It predicts that children may work because the net returns relative to alternative uses of time such as school attendance are low (compared with its cost) and the returns to work experience are relatively larger.
As such, biting into a richly stuffed layer cake, slurping up the cherry on top, can be an alternative form of time travel, triggering memories and urges and smells with every scrumptious bite.
As a second series of sensitivity analyses, we examined the effects of alternative smoothers of time, using either 3 or 6 df for time trend, as opposed to 4 df in the basic model.
We explored an alternative source of time constraints in teleostean phylogeny by evaluating a biogeographic hypothesis concerning freshwater fishes from the family Cichlidae (Perciformes: Labroidei).
Other approaches to combining alternative reporting of time to event data have been discussed [ 8, 23- 26], recommended [ 27] and implemented [ 28, 29].
