What is the z score for a 95% confidence interval? The z-score for a confidence level of 95% is 1.96. This value is based on how data is normally distributed.Understanding Confidence Interval (CI) One use of statistical analysis is the ability to make statistical inferences, which involves...
In this paper, we derive an explicit formula for constructing the confidence\ninterval of binomial parameter with guaranteed coverage probability. The\nformula overcomes the limitation of normal approximation which is asymptotic in\nnature and thus inevitably introduce unknown errors in applications. More...
They were based on the asymptotic maximum likelihood method and bootstrapping. Here, we propose a new confidence interval for R based on a modified signed log-likelihood ratio statistic. Simulation studies show that this interval outperforms those due to Kundu and Gupta....
