    • Least squares estimates of regression functions with certain monotonicity and concavity/convexity restrictions 

      Dahlbom, Ulla (University of Gothenburg, 1998-06-01)
      In all regression problems the choice of model and estimation method is due to a priori information about the regression function. In some situations it is motivated to consider regression functions with specific non-parametric ...
    • ON TESTS OF EQUIVALENCE 

      Holm, Sture; Dahlbom, Ulla (University of Gothenburg, 1990-02-01)
      We will study here a general method for constructing equivalence tests for problems with onedimensional or multidimensional parameter. In the biometric field, the equivalence tests have been studied by many authors under ...
    • PARAMETRIC AND NONPARAMETRIC TESTS FOR BXOEQUIVALENCE TRIALS 

      Dahlbom, Ulla; Holm, Sture (University of Gothenburg, 1986-02-01)
      In pharmacology, comparison of bioavailability is an important problem. A new formulation of a drug is compared with a standard formulation in human subjects. When the extent of absorption is studied the areas under the ...
    • Variance estimates based on knowledge of monotonicity and concavity properties 

      Dahlbom, Ulla (University of Gothenburg, 1998-08-01)
      In problems dealing with regression functions the choice of model and estimation method is due to a priori information about the regression function. In some situations it is motivated to consider regression functions with ...
