A difficulty associated with current hypothesis tests for generalized estimating equations is that, if the working correlation assumption is incorrect, then consistent estimates of the true covariance ...
The inverse probability weighted generalized estimating equations approach (Robins et al. 1994; Robins et al. 1995), effectively removes bias and provides valid statistical inference for regression ...
A categorical variable is defined as one that can assume only a limited number of values. For example, a person's sex is a categorical variable that can assume one of two values. Variables with levels ...
A new acentric factor correlation, based on Pitzer’s1 definition of the acentric factor and a correlation of Antoine’s equation,2 accurately predicts the acentric factor of hydrocarbons and other ...
