In the limit of long mean free path of the particles, the exact equation for the one-particle density matrix is simplified by introducing some general statistical properties of the residual interactions. An equation is obtained for the expectation values of operators which includes both the mean-...
of the advantage to be derived from the use of the weighbridge at live-stock markets in preference to buyers and sellers relying on their own judgments; but the letter raises several interesting points as to the theoretical treatment of statistical data, to two of which I should like to ...
We compare the expected lower confidence bounds of the two procedures with that of Dunnett''s procedure.

Besides its applicability to missing data situations due to non-response or attrition, the estimator can also be used for analyzing treatment effect heterogeneity and statistical treatment rules, where data on potential outcomes is missing by definition. By combining moments from a parametric ...

Importantly, this does not prove that living in these communities causes worse treatment outcomes. Mehaffey and colleagues1 in the accompanying article suggest that the dichotomized DCI is a multivariate predictor of adverse cardiac surgical outcomes in patients from distressed communities. This contention...
Factors such as alcohol use, nutritional status, socioeconomic status, hemoglobinopathies and treatment of comorbidities may lead to residual confounding. We did not collect data on menstruation, pregnancy, contraception use, and menopause, which are likely to impact hemoglobin and MCV among women. ...
of raw data from different sources and ranVLOOKUPS (an Excel function to find cross-references in the data) to join all that data to get a top-level look at the numbers. This worked well initially, but as the company’s sales and customer base were scaling rapidly, the data got larger...
ImportanceThe Kansas City Cardiomyopathy Questionnaire (KCCQ) is a commonly used outcome in heart failure trials. While comparing means between treatment groups improves statistical power, mean treatment effects do not necessarily reflect the clinical benefit experienced by individual patients....
Introduction The comparison of multiple group means using one-way ANOVA models is a commonly used approach in a wide variety of statistical studies. The term "one way" refers to a single factor containing an arbitrary number of groups or levels. In what follows, we will assume that the ...
