Are there coventions on reporting weighted sample sizes?
Suppose I analyze survey data and calculate weighted means. Should I report the sample size if it differs from the unweighted sample size, as would be the case with non-normalized weights? It seems ...

What is the (Ratio estimator for the) covariance of two weighted means? [closed]
In a previous question I've asked How to estimate the (approximate) variance of the weighted mean?, specifically, how to prove the following formula:
$$
\widehat{\sigma_{\bar{y}_w}^2} = \frac{1}{(\sum{...

How to estimate the (approximate) variance of the weighted mean?
Background: weighted mean
In the context of survey statistics it so happens that a sample of respondents from a survey are fit some weights to adjust their answers to the general population. These ...

How can I use Propensity Scores to adjust for survey non-response bias?
Say I estimate the probability that each member of my target population responds to a survey using propensity scores. I am having a hard time finding a clear explanation of how I can use the ...

How to decide if to use weights or not when estimating some $\mu$ of a population that has sub-populations with different $\mu_i$?
Setting and Notation
Let's assume we have a population with (for example) two sub-population. Say, males and females. In the population they are split 50%-50%. We care about the population level ...

How to (statistically) test for the difference in the mean of an outcome variable when using weights, vs not using them?
Notations
$y$ = outcome variable of interest.
$w$ = weights to use on outcome $y$ (estimated with some method, be it post-stratification, IPW, or something else)
$\bar y$ = summary statistic of ...

How to weigh samples (representative of population) when comparing group means
I want to clarify my understanding of using sample weights when comparing means of sub-groups of a sample.
Here is an artificial case with data that can be replicated in r (see code below):
Let’s ...

Permissible to use survey data in generating sampling weights?
Summary: Can I use non-population information (e.g. representative proportions from another survey) when calculating sampling weights? If so how might one account for the sampling error?
I'm ...
