Confidence intervals for ratios of means applied to corpus-based word frequency classes.

The words we choose when we communicate with one another convey meaning and information. In written or spoken language, we tend to employ a relatively small number of words repeatedly whereas a large number of words in the lexicon are seldom used. By considering a ratio of means of the most prevalent word in a body of texts (or corpus) compared to that of the word in question, one can quantify the prevalence of the word in question.

Activities of Daily Living Performance in Persons With Dementia: Comparing Care Partners' and Clinicians' Appraisal and Associated Factors.

Introduction: Persons living with dementia require assistance in making day-to-day and health care decisions. Health care professionals select treatments based on the care partner (CP) report of the person's function; however, the accuracy of CPs' appraisal has received limited exploration.

Methods: Retrospective analyses of observational, programmatic data were performed across 161 dyads (CPs and persons with dementia) participating in an evidence-based, community-level dementia intervention program.

Zero-inflated beta distribution applied to word frequency and lexical dispersion in corpus linguistics.

Corpus linguistics is the study of language as expressed in a body of texts or documents. The relative frequency of a word within a text and the dispersion of the word across the collection of texts provide information about the word's prominence and diffusion, respectively. In practice, people tend to use a relatively small number of words in a language's inventory of words and thus a large number of words in the lexicon are rarely employed.
