fixed-effect model

fixed-effect model

A statistical model that stipulates that the units being analysed—e.g. people in a trial or studies in a meta-analysis—are the ones of interest, and thus constitute the entire population of units. Only within-study variation is taken to influence the uncertainty of results (as reflected in the confidence interval) of a meta-analysis using a fixed-effect model. Variation between the estimates of effect from each study (heterogeneity) does not affect the confidence interval in a fixed-effect model (Cochrane definition).

The study also exploits the variation in spending within states over time to estimate a state fixed-effect model as a second test for bias.
In this study, a fixed-effect model was employed, where it assumed that each experiment in the series was a replication of the others, differing only in response scale and sample sizes.
If the analysis omits country-specific variables that correlate with the included regressors, then the fixed-effect model produces unbiased and consistent estimates of the coefficients.
