sdt.data2: Create data for 2 samples/groups

In gretat/sdt.rmcs: One line signal detection analysis

Description

This creates a dataset with 1000 participants to be used with the main function. rate.statistics2. It can be run with its defaults sdt.rmcs() or by specifying parameters.

Usage

sdt.data2(tot.signal = 85, tot.lure = 100, min.hits = 0.7, min.cr = 0.8,
  min.hits2 = 0.3, min.cr2 = 0.3)

Arguments

tot.signal	A number - The total number of signals i.e. blue dots that have to be detected Default = 85
tot.lure	A number - The total number of lures i.e. number green dots that should not be responded to, Default = 100
min.hits	A number - Minimum ammount of hits for group 1. Dafalt to 0.7
min.cr	A number - Minimum ammount of correct rejections for group 1. Dafalt to 0.8
min.hits2	A number - Minimum ammount of hits for group 2. Dafalt to 0.3
min.cr2	A number - Minimum ammount of correct rejections for group 2. Dafalt to 0.3

Value

A data table with the following columns

hits	total number of hits per participant randomly chosen between tot.signal and the minimum proportion hits specified
corRej	total number of correct rejection per participant randomly chosen between tot.lure and the minimum proportion critical rejections specified
miss	total number of misses per participant - left from the total signals after removing hits
falarm	total number of false alarms per participant - left from the total lures after removing correct rejections
hits2	total number of hits per participant for group 2 randomly chosen between tot.signal and the minimum proportion hits specified
corRej2	total number of correct rejection per participant for group 2 randomly chosen between tot.lure and the minimum proportion critical rejections specified
miss2	total number of misses per participant for group 2- left from the total signals after removing hits
falarm2	total number of false alarms per participant for group 2 - left from the total lures after removing correct rejections

Examples

    sdt.data2()
    sdt.data2(tot.signal = 100, tot.lure = 50,
          min.hits = 0.45, min.cr = 0.3,
          min.hits2 = 0.2, min.cr2 = 0.9)
