Sources of predictability

Sources of predictability

Sources of predictability in the basic laws of physics are described in the most general theoretical context — the quantum theory of the universe as a

Determinism and Sources of Predictability

In the article we find evidence that forecasts of music descriptor time series can still be performed at mid-term or relatively long horizons. In addition, we show that this ability becomes crucial for a real-world application, namely the automatic detection of cover songs. However, prediction errors are not as low as one would expect, even for short horizons. Thus, we here investigate in more ...

Facing environmental predictability with different sources of epigenetic variation

Different sources of epigenetic changes can increase the range of phenotypic options. Environmentally induced epigenetic changes and stochastic epimutations are, respectively, associated with phenotypic plasticity and diversifying bet-hedging. Their relative contribution is thus expected to reflect the capacity of a genotype to face distinct changes since these strategies are differentially sel...

On the Sources of Uncertainty in Exchange Rate Predictability∗

We analyse the role of time-variation in coeffi cients and other sources of uncertainty in exchange rate forecasting regressions. Our techniques incorporate the notion that the relevant set of predictors and their corresponding weights, change over time. We find that predictive models which allow for sudden, rather than smooth, changes in coeffi cients significantly beat the random walk benchma...
