What is the interpretation of weights here, and how are they calculated? Thanks! (PS: I know the weights input argument has a special meaning for binomial regression, in that it means the frequency of observations.
WebThe iterative weight turns out to be (B.18) w i = 1 / [ b ″ ( θ i) ( d η i d μ i) 2] = 1 n i π i ( 1 − π i) [ n i π i ( 1 − π i)] 2, and simplifies to (B.19) w i = n i π i ( 1 − π i). Note that the weight is inversely proportional to the variance of the working dependent variable. WebDec 1, 2024 · We can use the ipwpoint () function from ipw to generate continuous weights in one step. Instead of specifying a binomial treatment like we did before, we’ll use a Gaussian (normal) family. We also specify …
