By contrast, randomized error estimators, like cross-validation and bootstrap, have "internal" random factors that affect their outcome, and thus approximate approaches, usually via Monte Carlo sampling, are typically used to analyze their performance.

The paper " HyDEn: a hybrid steganocryptographic approach for data encryption using randomized error-correcting DNA codes" presented a novel hybrid DNA Encryption (HyDEn) approach that uses randomized assignments of unique error-correcting DNA Hamming code words for single characters in the extended ASCII set.
This would lead to the self-selection bias mentioned above and to randomized errors, since we worked with a statistical power which was less than desirable (type II error).
In randomized trials, random error may be one reason for the early stopping of trials at interim analyses when benefit or harm appear to be significant [ 32, 40].
Subjects were analyzed as randomized; there were no randomization errors in this subset.
Meta-analyses of randomized trials can, by reducing random errors and tending to minimize biases, provide more reliable estimates of the effects of a particular treatment strategy than any individual study.
The results of our systematic review with meta-analysis and trial sequential analysis show that randomized trials with low risk of systematic errors (bias) and low risk of random errors (play of chance) are needed.
As mentioned in the Introduction, we can categorize CoD estimators into non-randomized and randomized, depending on whether the prediction error estimator is non-randomized or randomized.
For the simple randomized design an alpha error of 0.05 and a beta error of 0.20 in a bilateral contrast are considered, requiring 204 pregnant women in the intervention group and 204 in the non intervention group to detect a difference greater than or equal to 15% in the prevalence of iodine deficiency between the two.
Routes to introduce diversity and increase the complexity of naïve libraries include: variation of CDRs via DNA shuffling [ 16], PCR using randomized primers, and random mutagenesis by error prone PCR [ 17] or dNTP analogs [ 18].
The system response obtained by numerical integration was treated as modal analysis data and the result is that the kurtosis-optimized excitation has compensated for the effect of nonlinearity and allowed to identify the damping ratio with good precision whereas an ordinary Gaussian excitation with randomized phases caused an error of 75percentt.
