We now evaluate the forecast performance of several mod- els for forecasting the quarterly CPI inflation rate at different horizons. The first five models are the ones we
This article investigates model characteristics that are consistent with variation in the shape of return distributions using a stochastic volatility model with a
Table 1 reports the null rejection probabilities for various two- sided 5% tests. It is clear that the tests based on the near-unity fixed-smoothing approximation are in general
However, out-of-sample tests are no panacea in this regard— the extent to which out-of-sample forecasting results are more reliable than in-sample forecasting results depends on the
We start from the simplest case, labeled FC-C, where factor and idiosyncratic volatilities are constant over the sample period (at high and low frequencies), and restrictions
For any loss function used, we compute four estimators, including the oracle estima- tor where the nonparametric and the parametric components are correctly specified with no
If the correlation between worker and firm effects is sufficiently high, then this can entail that the random effects of different workers at a given firm are correlated, and/or
For the expectation category the Cronbach’s alpha value for 14 service attributes was 0.963, hence it shows that the service attributes are internally consistent and each attribute is
