    • A brief overview of methods for synthetic data for official statistics 

      Steinbakk, Gunnhildur Högnadóttir; Langsrud, Øyvind; Løland, Anders (NR-notat;, Report, 2020-07-01)
      The access of quality data is valuable, and there is an increased attention to sharing data within the public sector and to other actors. Synthesising the data can be a way that satisfies both the requirements of preserving ...

    • A calibrated imputation method for secondary data analysis of survey data 

      Da Silva, Damiao N; Zhang, Li-Chun (Peer reviewed; Journal article, 2019-11-21)
      In practical survey sampling, missing data are unavoidable due to nonresponse, rejected observations by editing, disclosure control, or outlier suppression. We propose a calibrated imputation approach so that valid point ...

    • Graph sampling by lagged random walk 

      Zhang, Li-Chun (Peer reviewed; Journal article, 2021-12-10)
      We propose a family of lagged random walk sampling methods in simple undirected graphs, where transition to the next state (i.e., node) depends on both the current and previous states—hence, lagged. The existing random ...

    • Information preserving regression-based tools for statistical disclosure control 

      Langsrud, Øyvind (Peer reviewed; Journal article, 2019-01)
      This paper presents a unified framework for regression-based statistical disclosure control for microdata. A basic method, known as information preserving statistical obfuscation (IPSO), produces synthetic data that preserve ...

    • Methods library of embedded R functions at Statistics Norway 

      Langsrud, Øyvind (Journal article, 2017)
      Statistics Norway is modernising the production processes. An important element in this work is a library of functions for statistical computations. In principle, the functions in such a methods library can be programmed ...

    • Productivity Dispersion and Measurement Error 

      von Brasch, Thomas; Iancu, Diana-Cristina; Skjerpen, Terje (Peer reviewed; Journal article, 2019-11-11)
      Several reasons have been put forward to explain the high dispersion of productivity across establishments: quality of management, different input usage and market distortions, to name but a few. Although it is acknowledged ...

    • A Variance Estimation R-package for Repeated Surveys - Useful for Estimates of Changes in Quarterly and Annual Averages 

      Langsrud, Øyvind (Journal article, 2016)
      This paper presents a newly developed R-package for calculation of variances of estimates based on data from several waves of a repeated survey with partly overlapping samples. Development of the package is a part of ...
