In a controlled experiment, researchers meticulously manipulate one or more variables to determine their effect on another ...
Time-dependent variables can be used to model the effects of subjects transferring from one treatment group to another. One example of the need for such strategies is the Stanford heart transplant ...
The predicted frequencies table displays observed and predicted cell frequencies, their standard errors, and residuals.
Several models for limited dependent variables (variables having a non-negligible probability of exactly equaling zero) are examined. Estimation in and discrimination among the various models are ...
Using Ecological Inference Point Estimates as Dependent Variables in Second-Stage Linear Regressions
The practice of using point estimates produced by the King ecological inference technique as dependent variables in second-stage linear regressions leads to second-stage results that, in general, are ...
In science, a variable is something that can be changed, measured or controlled in an experiment. Scientists look at variables to understand how they affect things. A variable is any one of the things ...
