Raking survey weights
WebbCalibration, generalized raking, or GREG estimators generalise post-stratification and raking by calibrating a sample to the marginal totals of variables in a linear regression model. This function reweights the survey design and adds additional information that is used by svyrecvar to reduce the estimated standard errors. The analysis compares three primary statistical methods for weighting survey data: raking, matching and propensity weighting. In addition to testing each method individually, we tested four techniques where these methods were applied in different combinations for a total of seven weighting methods: Raking … Visa mer For public opinion surveys, the most prevalent method for weighting is iterative proportional fitting, more commonly referred to as raking. With raking, a researcher chooses a … Visa mer Matching is another technique that has been proposed as a means of adjusting online opt-in samples. It involves starting with a sample of cases … Visa mer Some studies have found that a first stage of adjustment using matching or propensity weighting followed by a second stage of adjustment … Visa mer A key concept in probability-based sampling is that if survey respondents have different probabilities of selection, weighting each case by the inverseof its probability of selection removes any bias that might result from … Visa mer

WebbMany data analysts use survey data and understand the general purpose of survey weights. However, they may not have studied the details of how weights are computed, nor do they understand the purpose of different steps used in weighting. Survey Weights: A Step-by-step Guide to Calculation is intended to fill these gaps in understanding. Webbhave from doing the full weighting. BUT sometimes we don’t want to or can’t do the full weighting. Using raking weights or not poststratifying regression results based on the full population contingency table can cause weighting and regression to give different estimates. Here we try to fig ure out when and why these two estimates are most
