چکیده
this article aims to provide a simple robust method to test the parameters of a normal population by using the new diagnostic tool called the “forward search” (fs) method. the most commonly used procedures to test the mean and variance of a normal distribution are student’s t test and chi-square test, respectively. these tests suffer from the presence of outliers. we introduce the fs version of these tests that is not affected by the outliers. the performances of these procedures are illustrated by some simulation studies and a real data example.

15 صفحه اولEvaluation of Cardiopulmonary Exercise Testing (CPET) Parameters in Normal Adult Population
Background: Cardiopulmonary exercise testing (CPET) is a widely applied clinical procedure. The aim of the present study was to acquire a comprehensive set of reference values for cardiopulmonary responses to exercise and to evaluate the possible associations with sex, age and body mass index (BMI). Methods: From files of 3,992 CEPT performed in the hospital during six years, 102 files of heal...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Testing the Exactitude of Estimation Methods in the Presence of Outliers: An accounting for Robust Kriging
Estimation of gold reserves and resources has been of interest to mining engineers and geologists for ages. The existence of outlier values shows the economic part of the deposits subject to the fact that don’t depend on the human or technical errors. The presence of these high values causes a pseudo dramatically increment in variance estimation of economical blocks when applying conventional m...
متن کاملHYPOTHESIS TESTING FOR AN EXCHANGEABLE NORMAL DISTRIBUTION
Consider an exchangeable normal vector with parameters ????2, and ?. On the basis of a vector observation some tests about these parameters are found and their properties are discussed. A simulation study for these tests and a few nonparametric tests are presented. Some advantages and disadvantages of these tests are discussed and a few applications are given.
