The purpose of this study is to investigate the impact of estimation techniques and sample sizes on model fit indices in structural equation models constructed according to the number of exogenous latent variables under multivariate normality. The performances of fit indices are compared by considering effects of related factors. The Ratio Chi-square Test Statistic to Degree of Freedom, Root Me...

We introduce an adjusted likelihood ratio procedure for computing pointwise confidence intervals for survival functions from censored data. The test statistic, scaled by a ratio of two variance quantities, is shown to converge to a chi-squared distribution with one degree of freedom. The confidence intervals are seen to be a neighborhood of a semiparametric survival function estimator and are s...

Notation. we conform to the convention that random variables shall be denoted by capital letters, whilst constants and observed values of random variables be denoted by lowercase letters. If X is a random variable with a continuous and strictly increasing (cumulative) distribution function over its range, then the unique upper γ point ofX will be denoted byXγ , i.e. Pr{X ≥ Xγ} = γ. The sole exc...
