A lineup is supposed to consist of a\nsuspect and a number of additional members, or foils, whom a\npoor-quality witness might mistake for the perpetrator). Lineup\nmeasures are descriptive, in the first instance, but since the\nearliest articles in the literature researchers have recognised\nthe importance of reasoning inferentially about them. This\npackage contains functions to compute various properties of\nlaboratory or police lineups, and is intended for use by\nresearchers in forensic psychology and/or eyewitness testimony\nresearch. Among others, the r4lineups package includes\nfunctions for calculating lineup proportion, functional size,\nvarious estimates of effective size, diagnosticity ratio,\nhomogeneity of the diagnosticity ratio, ROC curves for\nconfidence x accuracy data and the degree of similarity of\nfaces in a lineup.", "License": "CC0", "Encoding": "UTF-8", "LazyData": "true", "RoxygenNote": "6.0.1.9000",
