abstract objectives, the purpose of this research was to evaluate of the intra-rater and inter-raters reliability of the 10 meter walk test (10 mwt) in 30 adults with spastic cerebral palsy (cp) with subgroup analyses in gross motor function classification system (gmfcs). material & methods, participants  (19 men, 11 women; mean age 27 y and 9 mo) with gmfcs levels below iv (i, ii, and iii) non...

The problems of testing a normal covariance matrix and an interval estimation of generalized variance when the data are missing from subsets of components are considered. The likelihood ratio test statistic for testing the covariance matrix is equal to a specified matrix, and its asymptotic null distribution is derived when the data matrix is of a monotone pattern. The validity of the asymptoti...

In this paper, we show that the difference between empirical estimator and Conditional value-at-risk can be written as a simple partial sum + residual term. Starting from decomposition, prove central limit theorem some almost sure results for estimator, large class of stationary sequences. We also construct confidence interval with asymptotic level 1−α, study its coverage through two different ...

The forecast is very complex in financial markets. The reasons for this are the fluctuation of financial data, Such as Stock index data over time. The determining a model for forecasting fluctuations, can play a significant role in investors deci-sion making in financial markets. In the present paper, the Black Scholes model in the prediction of stock on year later value, on using data from mel...

The problem of setting a confidence interval with fixed proportional accuracy for the mean of a normal distribution is considered. A sequential procedure is proposed; and asymptotic expansions for its average coverage probabilities and its expected sample size are obtained. The procedure is shown to have asymptotically minimal expected sample size, subject to a constraint on the error probabili...

Background/Aim. It is necessary to decide whether the newly improved methods are better than the standard or reference test or not. To decide whether the new diagnostics test is better than the gold standard test/imperfect standard test, the differences of estimated sensitivity/specificity are calculated with the help of information obtained from samples. However, to generalize this value to th...

ASYMPTOTICS AND CONFIDENCE ESTIMATION IN SEGMENTED REGRESSION MODELS Rebekah Ann Robinson May 11, 2012 Standard regularity assumptions for regression models are not satisfied in segmented regression models with an unknown change point, and consequently standard asymptotic results and inferential methods for confidence estimation are not applicable. This dissertation considers a clustered segmen...
