Asúlyozás
Asúlyozás is a process of assigning weights to elements to reflect their relative importance, frequency, or reliability. It is used in statistics, data analysis, decision making, and data processing to ensure that certain observations, criteria, or features contribute more or less to a result than others.
In statistics and survey methodology, weighting adjusts for unequal selection probabilities and response rates, producing estimates
In meta-analysis, inverse-variance weighting combines study estimates to obtain a pooled effect size, with more precise
Weights can be determined a priori from subject-mmatter expertise or empirically using data-driven methods, such as
Caution is warranted because the choice of weights can affect conclusions and introduce bias if not justified
