Optimal Design When Outcome Values Are Not Missing at Random
The presence of missing values complicates statistical analyses. In design of experiments, missing values are particularly problematic when constructing optimal designs, as it is not known which values are missing at the design stage. When data are missing at random it is possible to incorporate this information into the optimality criterion that is used to find designs; Imhof, Song, and Wong (...
متن کاملRobust Regression Estimators When There are Tied Values
There is a vast literature on robust regression estimators, the bulk of which assumes that the dependent (outcome) variable is continuous. Evidently, there are no published results on the impact of tied values in terms of the Type I error probability. A minor goal in this paper to comment generally on problems created by tied values when testing the hypothesis of a zero slope. Simulations indic...
متن کاملEstimating ratio scale values when units are unspecified
Multiplication of a ratio scale by a positive constant (a similarity transformation) causes the values to change to a different unit of measure without upsetting relative ratios between objects. Because the relative ratios of any two objects are uniquely represented, a column vector estimating the same objects can be expressed as a comparison matrix which has no effect of any similarity transfo...
متن کاملTechnical note: acceptability curves could be misleading when correlated strategies are compared.
T recent discussions1 3 on the limitation of the cost-effectiveness acceptability curves (CEACs) was helpful in reevaluating the value of CEACs in cost-effectiveness studies. One of the limitations of the CEACs, as pointed out by Groot Koerkamp and colleagues1 as well as other authors,4,5 is that they may mislead policy makers regarding the preferred alternative. This refers to the fact that th...
متن کاملWhen measurements are misleading: modelling the effects of blood pressure misclassification in the English population.
Guidelines recommend that primary care teams measure their adult patients’ blood pressures. Is this always a useful activity? A measurement of blood pressure is an estimate of the true mean blood pressure. Clinical decisions are based on the average of several measurements. However, measurement is imperfect, and blood pressure shows random biological variation from beat to beat. Because of this...
