Varloglog
Varloglog is not a widely defined term in formal mathematics or computer science. In published material it is typically encountered as a nonstandard label whose meaning depends on the context. Possible interpretations include: (1) a shorthand for the variance of data after applying a log transformation, sometimes extended to a double-log form such as var(log(log(x))) to stabilize variance for highly skewed, multiplicative data; (2) analysis of variance on data plotted in a log-log (both axes logarithmic) coordinate system, used when examining relationships that follow a power law; in that case varloglog might refer to the residual variance of a log-log regression; or (3) a software concept, where varloglog is the name of a function, module, or library that handles variance estimation or plotting on log-scale domains. In practice, the exact definition is determined by the author and the surrounding mathematical or programming framework. When encountering varloglog, readers should consult the source for the intended meaning, including definitions, formulas, and units.
