One-sided tolerance limits for the normal distribution, p = 0.80, ? = 0.80

' - 080 f £ discussion paper

This report documents the results of two follow-up workshops on the International Handbook of Labour Market Policy and Evaluation. The aim of these workshops was the exchange of experience among academics and practitioners in the evaluation of labour market policies. The Handbook project as well as the two workshops were supported from the beginning by DG V of the European Commission through th...

ON THE POWER FUNCTION OF THE LRT AGAINST ONE-SIDED AND TWO-SIDED ALTERNATIVES IN BIVARIATE NORMAL DISTRIBUTION

This paper addresses the problem of testing simple hypotheses about the mean of a bivariate normal distribution with identity covariance matrix against restricted alternatives. The LRTs and their power functions for such types of hypotheses are derived. Furthermore, through some elementary calculus, it is shown that the power function of the LRT satisfies certain monotonicity and symmetry p...

The Lens Galaxy in Pg1115+080 Is an Ellipse

We use the structure of the Einstein ring image of the quasar host galaxy in the four-image quasar lens PG1115+080 to determine the angular structure of the gravitational potential of the lens galaxy. We find that it is well described as an ellipsoid and that the best fit non-ellipsoidal models are consistent with the ellipsoidal model. We find upper limits on the standard parameters for the de...

Two-Sided Tolerance Interval for Exponential Distribution Based on Records

Tolerance interval is a random interval that contains a proportion of the population with a determined confidence level and is applied in many application fields such as reliability and quality control. In this paper, based on record data, we obtain a two-sided tolerance interval for the exponential population. An example of real record data is presented. Finally, we discuss the accuracy of ...
