| However, this optimality property does not hold for heteroscedastic models. |
|
| Sometimes if noise was shown to be heteroscedastic, data was scaled to overcome this limitation. |
|
| The nature of Earth's magnetic field is one of heteroscedastic fluctuation. |
|
| The residuals are neither autocorrelated nor heteroscedastic and display no significant deviations from the normal distribution. |
|
| Statistical analysis was performed using a one-tailed distribution, heteroscedastic t-test. |
|
| To overcome this problem we introduced heteroscedastic extreme value model, probit model and mixed-logit model. |
|
| Square-root heteroscedastic shocks to the factors are possible sources of risks priced by the market, allowing both inflation-risk premiums and real-term premiums to vary over time. |
|
| General autoregressive conditional heteroscedastic models explicitly take account of non-linearity in stock market volatility. |
|
| Multiple range test for correlated and heteroscedastic means. |
|
| The second issue concerns the presence of heteroscedastic errors. |
