The Lienert LSD Data

Description

Data from the classical Lienert LSD trial as an example for CFA (see Lienert, 1971, p. 103, ’Tabelle 1’). The data is in pattern frequencies table representation (object of class c("data.frame", "Pfreq" )).

Usage

  data(LienertLSD)

Format

A data frame (object of class c("data.frame", "Pfreq") ) with 4 columns and 8 rows. The last column gives the frequencies for the observed pattern of the psychotoxic basic syndrome (in column 1:3) due to the intake of lysergic acid diethylamide (LSD).

Details

The first three columns are named C, T and A which are abbreviations for the observed symptoms after taking LSD:

C = narrowed consciousness

T = thought disturbance

A = affective disturbance

The coding of the observations is for all symptoms: present='+' and absent='-'
