Usage

2

Format

A data frame with 1387 observations on the following 3 variables.

Orient

a numeric vector

Involv

a numeric vector

Attitude

a numeric vector

The format of attitudeStartingValues is: num [1:7] 0.153 -0.453 -0.097 -0.124 -0.227 ...

Details

The data set was taken from (van der Maas, Kolstein, & van der Pligt, 2003). It concerns attitudinal response transitions with respect to the statement “The government must force companies to let their workers benefit from the profit as much as the shareholders do”. Responses of some 1387 Dutch respondents are included who indicated their level of agreement with this statement on a 5 point scale (1 = total ly agree, 5 = total ly disagree). As a normal factor political orientation (measures on a 10 point scale from 1 = left wing to 10 = right wing) was used. As a bifurcation factor the total score on a 12 item political involvement scale was used. The theoretical social psychological details are discussed in (van der Maas et al. 2003).

The starting values provided here for a cusp analysis of the attitude data set give proper convergence in one run. They were found after many trial starting values that yielded improper convergence.
