Sentence examples for estimates item from inspiring English sources

Descriptive analyses of primary process of care indicators with confidence intervals around point estimates (item-by-item measurement) were conducted, taking into account the hierarchical structure of the data (clusters of pharmacies).

We then assessed items by using classic test theory and IRT, used confirmatory factor analyses to estimate item parameters, and graded response modeling for parameter estimation.

One example of this is joint maximum likelihood estimation in IRT where estimates of ability are used to estimate item parameters (and vice versa).
