    Författare :Björn Andersson; Fan Yang-Wallentin; Marie Wiberg; Alina A. von Davier; Jorge González; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; observed-score test equating; item response theory; R; equipercentile equating; asymptotic standard errors; non-equivalent groups with anchor test design; Statistics; Statistik;

    Sammanfattning : The statistical practice of equating is needed when scores on different versions of the same standardized test are to be compared. This thesis constitutes four contributions to the observed-score equating framework kernel equating. LÄS MER

  3. 7. VAR Models, Cointegration and Mixed-Frequency Data

    Författare :Sebastian Ankargren; Johan Lyhagen; Yukai Yang; Gregor Kastner; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; vector error correction; small open economy; mixed-frequency data; Bayesian; steady state; nowcasting; state-space model; large VARs; simulation smoothing; factor stochastic volatility; R; Statistics; Statistik;

    Sammanfattning : This thesis consists of five papers that study two aspects of vector autoregressive (VAR) modeling: cointegration and mixed-frequency data.Paper I develops a method for estimating a cointegrated VAR model under restrictions implied by the economy under study being a small open economy.
