Reason for variable response to tine test In comparative studies with the Mantoux test the tine method has shown false-negative rates of between 23% and 64%,1-though studies on highly sensitised tuberculous patients have tended to show a closer correlation.4 This inconsistency has remained unexplained by studies of the duration of application, skin temperature, and release of skin tension befor...

Statistical inference is based generally on some estimates that are functions of the data. Bootstrapping procedure offers strategies to estimate or approximate the sampling distribution of a statistic. Logistics regression model with binary response is commonly used. This paper focuses on the behavior of bootstrapping pseudo R 2 measures in logistic regression model. Simulation and real data re...

In this article, we propose new Bayesian methods for selecting and estimating a sparse coefficient vector for skewed heteroscedastic response. Our novel Bayesian procedures effectively estimate the median and other quantile functions, accommodate non-local prior for regression effects without compromising ease of implementation via sampling based tools, and asymptotically select the true set of...

To find he precursor of contemporary latent variable modelling one must go back to the beginning of the 20th century and Charles Spearman’s invention of factor analysis. This was followed, half a century later, by latent class and latent trait analysis and, from the 1960’s onwards, by covariance structure analysis. The most recent additions to the family have been in the area of time series. We...
