%description
Applies the change-in-effect estimate method to assess confounding effects
in medical and epidemiological research (Greenland & Pearce (2016)
<doi:10.1146/annurev-publhealth-031914-122559> ). It starts with a crude
model including only the outcome and exposure variables. At each of the
subsequent steps, one variable which creates the largest change among the
remaining variables is selected. This process is repeated until all
variables have been entered into the model (Wang Z. Stata Journal 2007; 7,
Number 2, pp. 183–196). Currently, the 'chest' package has functions for
linear regression, logistic regression, negative binomial regression, Cox
proportional hazards model and conditional logistic regression.
