LBvalue

LBvalue is a term that appears in the context of statistical hypothesis testing, specifically related to the concept of p-values. While not a standard or widely recognized term in mainstream statistical literature, it seems to be a custom or internal notation used by some researchers or in specific software packages.

When encountering "LBvalue," it is likely intended to represent a lower bound on a p-value or a value derived from a test statistic that is then compared to a critical value to determine statistical significance. In traditional hypothesis testing, a p-value is the probability of observing a test statistic as extreme as, or more extreme than, the one observed, assuming the null hypothesis is true. If this p-value is less than a predetermined significance level (alpha), the null hypothesis is rejected.

The "LB" prefix could suggest a calculation that provides a guaranteed minimum p-value under certain assumptions, or perhaps it relates to a Bayesian approach where it might represent a lower bound on a posterior probability or a related metric. Without further context specific to where "LBvalue" is used, its precise meaning remains ambiguous. It is advisable to consult the documentation or the authors who introduced this term for a definitive explanation. The standard terminology in frequentist statistics remains p-value, and in Bayesian statistics, concepts like posterior probability, credible intervals, and Bayes factors are commonly used.
