    Keywords : HUMANIORA; HUMANITIES; Engelska språk och litteratur ; English language and literature; error gravity; proper noun; identification frame; genericness; the zero article; ‘idiomatic’ prepositional use; ‘systematic’ prepositional use; ‘basic’ prepositional use; non-contiguous subject-verb construction; contiguous subject-verb construction; subject-verb concord; fossilisation; restructuring of information; automatisation; interlanguage; cognitive second language acquisition theory; U-curve development; regression; progression; developmental pattern; relative frequency; error score; potential error; developmental continuum; advanced learner; Grammar; semantics; semiotics; syntax; Grammatik; semantik; semiotik; Applied linguistics; foreign languages teaching; sociolinguistics; Tillämpad lingvistik; undervisning i främmande språk; sociolingvistik;

    Abstract : This thesis investigates advanced Swedish students’ development of three grammatical phenomena: subject-verb concord, prepositions and article use in compositions and translations. In order to describe the students’ development of these categories, actual errors are related to potential errors forming so called ‘error scores’. READ MORE

  4. 2. Observed score equating with covariates

    Author : Kenny Bränberg; Marie Wiberg; Xavier de Luna; Dag Sörbom; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Equating; observed score equating; true scores; item response theory; linear equating function; equipercentile equating; kernel equating; covariates; linear regression; mean squared error; Statistics; Statistik; Statistics; statistik;

    Abstract : In test score equating the focus is on the problem of finding the relationship between the scales of different test forms. This can be done only if data are collected in such a way that the effect of differences in ability between groups taking different test forms can be separated from the effect of differences in test form difficulty.

  5. 3. Identifying Influential Observations in Nonlinear Regression : a focus on parameter estimates and the score test

    Author : Karin Stål; Tatjana von Rosen; Sune Karlsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Added parameter plot; differentiation approach; influential observation; nonlinear regression; score test; Statistics; statistik;

    Abstract : This thesis contributes to influence analysis in nonlinear regression and in particular the detection of influential observations. The focus is on a regression model with a known mean function, which is nonlinear in its parameters and where the function is chosen according to the knowledge about the process generating the data.

  6. 4. Tests of random effects in linear and non-linear models

    Author : Erling Häggström Lundevaller; Umeå universitet; []
    Keywords : Random effects; score test; NLS; heteroskedasticity; measurement error; Poisson regression; trip frequencies; Statistics; statistik;

  7. 5. Extensions of the kernel method of test score equating

    Author : Gabriel Wallin; Marie Wiberg; Jenny Häggström; Anton A. Béguin; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Test equating; Nonequivalent groups; Standard error of equating; bandwidth selection; log-linear models; item response theory; Statistics; statistik;

    Abstract : This thesis makes contributions within the area of test score equating and specifically kernel equating. The first paper of this thesis studies the estimation of the test score distributions needed in kernel equating. READ MORE
