Attalea (plant) important economically. Products extracted from "A. speciosa" were reported to support over 300,000 households in the Brazilian state of Maranhão in 2005, and in 1985 it was estimated to support over 450,000 households throughout the Brazil. Piassava fibres, extracted from the leaf bases of "A. funifera", are commercially important, and generated about US$20 million in annual income to Brazilian farmers in 1996. Attalea (plant) Attalea is a large genus of palms native to Mexico, the Caribbean, and Central and South America. This pinnately leaved, nonspiny genus includes both small palms lacking an aboveground stem and large trees. The genus has
Average variance extracted heterotrait-monotrait ratio (HTMT). Related coefficients are tau-equivalent reliability (formula_7; traditionally known as "Cronbach's formula_8") and congeneric reliability (formula_9; also known as composite reliability) which can be used to evaluate the reliability of tau-equivalent and congeneric measurement models, respectively. Average variance extracted In statistics (classical test theory), average variance extracted (AVE) is a measure of the amount of variance that is captured by a construct in relation to the amount of variance due to measurement error. The average variance extracted was first proposed by Fornell & Larcker (1981). The average variance extracted can be calculated as follows: Here, formula_2 is the
