Interpretation. Example. Between 0 and 1. Positive correlation. When one variable changes, the other variable changes in the same direction. Webthe analysis is more robust than the assumptions, and sensibly interpreted will provide useful results even if some assumptions fail. Further, there are often relatively simple estimation alternatives that provide some protection against failures, such as use of instrumental variables or heteroskedasticity-consistent sta ndard errors.

WebMar 8, 2011 · Doubly robust estimation combines a form of outcome regression with a model for the exposure (i.e., the propensity score) to estimate the causal effect of an exposure on an outcome. When used individually to estimate a causal effect, both outcome regression and propensity score methods are unbiased only if the statistical model is … Robust statistical analyses can produce valid results even when the ideal conditions do not exist with real-world data. These analyses perform well when the sample data follow a variety of distributions and have unusual values.
