  Climate‐induced drought is accelerating the degradation of alpine grasslands, which cover 50%–60% of the Qinghai–Tibetan Plateau and provide critical ecosystem services including biodiversity conservation, carbon storage, and forage production. Degradation and recurrent drought events can reduce aboveground biomass by up to 73%, severely impairing soil function and ecosystem stability. This review highlights biochar as a nature‐based solution (Nb…

• A Model Fit Statistic for Generalized Partial Credit Model

  Open Access•Tie Liang, Craig S Wells•ARTICLE•Educational and Psychological…•2009

  Investigating the fit of a parametric model is an important part of the measurement process when implementing item response theory (IRT), but research examining it is limited. A general nonparametric approach for detecting model misfit, introduced by J. Douglas and A. S. Cohen (2001), has exhibited promising results for the two-parameter logistic model and Samejima s graded response model. This study extends this approach to test the fit of gener…
