Naive estimates for CUBE models without covariates

Compute naive parameter estimates of a CUBE model without covariates for given ordinal responses. These preliminary estimators are used within the package code to start the E-M algorithm.

inibestcube(m,ordinal)

Arguments

• m: Number of ordinal categories
• ordinal: Vector of ordinal responses

Returns

A vector $(\pi, \xi ,\phi)$ of parameter estimates of a CUBE model without covariates.

Examples

data(relgoods)
m<-10
ordinal<-relgoods$SocialNetwork
estim<-inibestcube(m,ordinal)     # Preliminary estimates (pai,csi,phi)
