CircE (version 1.1)

Block: Intercorrelation of Emotions in a Female Sample (N=48)

Description

The Osgood's "semantic differential" form was administered to 40 male and 48 female college students in an undergraduate psychology course. Fifteen emotions, selected a priori but with the intention of comprehensive coverage of the affective sphere, were used as the concepts to be defined. Each concept was evaluated in terms of twenty connotative 7-point scales. The intercorrelations matrix based upon the female sample is given in this object.

# Block.m.1<-CircE.BFGS(R=Block,v.names=block.names,m=1,N=48,start.values="IFA")
# # You will get the following warnings:
# # WARNING! 
# # INPUT COVARIANCE/CORRELATION MATRIX IS NOT POSITIVE DEFINITE. 
# # STARTING VALUES CANNOT BE COMPUTED USING 'IFA': SET start.values='PFA' 
# # Error in ifa(R, k) : 
# # Make sure the listwise, not pairwise, missing data treatment has been selected 
# # in computing the input matrix
# #
# # The error message reported by CircE highlights that the problem in fitting a CSPMF 
# # to Block's data occurs at the early stage of starting values computation. 
# # CircE offers a way to sidestep this problem without actually trying to discern its cause: 
# # In fact, at this stage, the IFA cannot be carried out since the inverse of the 
# # non-positive definite Block's matrix has negative values 
# # on the diagonal (Joreskog, 1969, p. 54): 
# 
# 
# diag(solve(Block))
# 
# # To overcome this problem, CircE offers an alternative ways to obtain initial 
# # parameters estimation, based on Principal Factor Analysis (PFA):  
# 
# Block.m.1<-CircE.BFGS(R=Block,v.names=block.names,m=1,N=48,start.values="PFA")
