Although the shrinkage estimators are biased, they have smaller variances than do the community-specific estimators, thus providing more stable estimates of risk over time.
An estimation scheme is developed whereby exponentially stable estimates of the unknown parameters can be obtained with an arbitrarily large region of attraction.
Efficient numerical algorithms are a focus of our discussion, which are responsible for recovering stable estimates of the sparse signals in high-dimensional space.
Compared with data splitting, nested cross-validation results in better models and more stable estimates of performance, since every subject contributes to the performance estimates.
Of the three types of predictors, those related to observable physical damage to key structural components produced the most accurate and stable estimates of aftershock collapse vulnerability.
Of note, the number of deaths per level of sleep duration was relatively small in these stratified analyses (models with depressed women: ndeaths=8 36), leading to less stable estimates with wider CIs.
Using National Epidemiological Survey data, they demonstrate that ACCRA data fail to yield stable estimates of beer price elasticities.
We repeated the simulation 200 times to produce stable estimates of the median, 5th and 95th percentiles for the measurements presented below.
To obtain stable estimates of the Im and to capture as many important interactions as possible, the analyses were performed with a large number of trees (40,000).
However, as recommended by the National Center for Health Statistics, we combined data from three cycles in order to obtain stable estimates.
One million patients are simulated, one at a time, in order to provide stable estimates of long-term outcomes for each strategy.
