we may have a good estimator at n n =20, but it may be terrible at n n =2000; there's more effort required, in some sense, if we want to use inconsistent estimators as a matter of course. if you use lad to estimate the mean of an exponential, it won't be...
In general, bulls with an SCE of 8% or less are considered “calving ease” bulls that are fine to use on heifers and smaller cows. Bulls with a high SCE percentage should be used with caution on heifers and smaller cows, as they have a higher percent chance of siring larger calves ...

Researchers led by Christopher P. Cannon, MD, of Brigham and Women’s Hospital (Boston, MA), looked at 18,144 moderate- to high-risk patients (mean age 63.6 years; 75.7% men) stabilized after a recent ACS event who had LDL levels below 125 mg/dL (or 100 mg/dL if on chronic st...
When only time from symptom onset was used, the mRs distribution more skewed to lower values but nevertheless different form the unselected sample (p = 0.02). When both criteria were used, the distribution was less skewed with a median mRs of 3 and also significantly different form the whole...
We evaluated model performance relating to a selection of learning metrics, such as the mean location under the receiver running characteristic curve [AUROC]. We also utilized the Shapley additive explanation algorithm to describe the forecast model. Results device learning models making use of laborato...

A variety of combination methods have been proposed in an attempt to solve the problem. Statistical average techniques (e.g. the mean, trimmed mean, and median methods) have been proved useful in some special contexts (Blanc & Setzer, 2016; Hsiao & Wan, 2014), while more complex combination...
So it is important to keep in mind that I am discussing the specific framing of the arithmetic mean versus the median in introductory applied statistics (where, mode aside, other measures of central tendency are not motivated). Rather than judging the utility of the mean by how much it ...
sub-scale. The proportion of the sample for each sub-scale with imputed values varied from 2% to 9%. Imputation had minimal impact on mean/median values. Throughout, proportions were calculated with the dominator being all participants who answered the questions excluding those who said “n/a...
