WebJul 1, 2015 · When using propensity scores for inverse probability weighting (IPW) the standard errors for the parameters in the regression model may be affected. I have seen several examples of people using different types of standard errors (classical, robust, bootstrap) and am unsure which ones are correct to use and why. WebR: Adjusted Survival Curves by Using IPW. A numeric vector with the follow up times. A numeric vector with the event indicators (0=right censored, 1=event). A numeric vector with the binary variable under interest (only two groups). The weights for correcting the contribution of each individual. i don\u0027t want to talk about it コード
