Sago monitor Sago monitor The sago monitor or torch monitor, Varanus obor, is a species of monitor lizards endemic to the Indonesian island of Sanana. "Varanus obor" is the only melanistic member of the Pacific monitor ("V. indicus") group, and the only species belonging to the subgenus "Euprepiosaurus", which has prominent red-orange markings on its body. Proportions of the body and the construction of scales most closely resemble "V. melinus", which can be found on the islands of Mangole and Taliabu. Most often, "V. obor" occurs in coastal sago palm swamps - a habitat that is underused by other species of the
Average variance extracted 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 number of items, formula_3 the factor loading of item formula_4 and formula_5 the variance of the error of item formula_4. The average variance extracted has often been used to assess discriminant validity based on the following "rule of
