kind of variable do we want to express our test statistic in. Let us suppose that we are collecting the blood group of people. In this case, are variable will be the nominal level of measurement. In other cases, we can choose either the ordinal, interval or ratio level of measu...
independent level detection system,marked by it,that a measuring and evaluation device with electrical energy storage is installed in a liquid -tight housing,\nthat it can be placed in the liquid of any liquid container independently and without any mechanical or electrical connection and, if ...
All Decision-Making Units (DMU) production activities are usually assumed to be fully efficient or at the edge of the Production Possibility Frontier (PPF). Such a perfect efficiency assumption simplifies measurement’s complexity, but it also brings some problems. Although many economic models ...
The model assumes a linear eflect of each independent variable as well as a series of break points between categories for the dependent variable. Maximum likelihood estimators are found for these parameters, along with their asymptotic sampling distributions, and an analogue of R (the coefficient ...
The devices used in the measurement of body height and weight were all calibrated regularly under the hospitals’ standard operating procedures. Obesity in this study was defined as body mass index (BMI) ≥ 27 kg/m2, according to the Ministry of Health and Welfare of Taiwan. The ...
The plunger impact shear test with its ability to measure the impact force and displacement is favourable over the other two test methods; the pendulum impact shear test is susceptible to measurement errors due to the elastic deformation of the pendulum, while the ball impact pull test is ...
the authors have introduced a new measurement unit called currentcy. One unit of currentcy represents the right to consume a certain amount of energy during a fixed period of time. When the user sets the target battery lifetime and prioritizes the applications, ECOsystem transforms these data in...

In multiple myeloma spatial differences in the subclonal architecture, molecular signatures and composition of the microenvironment remain poorly characterized. To address this shortcoming, we perform multi-region sequencing on paired random bone marrow
Upon enrollment, all participants gave written informed consent for participation and for reuse of their data. In all groups (HC, MCI, and AD), the Altoida DNS test was administered every 6–8 months over 2 days; day 1 included training and a first measurement, and day 2 included a “re...
