Can a covariate be a categorical/nominal variable, or should it be a continuous/scale/ratio variable? I ask this because in SPSS you are required to enter...

Currently, the first occurrence of 'covariate' links to the wikipedia article for 'co-variance'; which does not refer to covariate, and -to my best understanding-...

unknown distribution P, where X ∈ R p {\displaystyle X\in \mathbb {R} ^{p}} covariates A ∈ { 0 , 1 } {\displaystyle A\in \{0,1\}} Y ∈ R {\displaystyle Y\in \mathbb...

edits) For any fixed covariate, the law of large numbers suggests that the method of random assignment has balance on that covariate, and large-deviation...

the type where cohorts are defined or selected according to baseline covariates. The classical example of a cohort study is one where a group of smokers...

each of the terms “idiosyncratic,” “regional covariant” and “nation-wide covariate” would be useful to increase clarity. The chart, however, is very useful...

practice uses the two-parameter ZIP model. It almost always involves covariates/regressors. Model and estimation part should reflect that (Maximum Likelihood)...

means the "parameters" are not linearly dependent when ought to say "covariates," it claims the errors must have a mean of zero and spherical distributions...

It seems that the sections "Multiple and mixed covariates" and "Calculating the baseline hazard" are empty. The sections should either be filled in or...

means that covariance should be replaced with something like mean covariate, where covariate would mean the product of two variates. This actually is similar...

estimated. The reason is that researchers are often interested in how covariates might influence survival, and these may be time varying, e.g. smoking...

scores became non-significant when we adjusted for depression scores for covariates. This suggests that the depression and anxiety scores are highly intercorrelated...

These relative risks were applied to the distribution of BMI and other covariates from NHANES 1999-2002 to estimate attributable fractions and number of...

the piece should not claim that one reason that the error term and the covariates may be correlated is endogeneity! 68.146.25.175 (talk) 22:28, 20 April...
