Usage

1

Format

A table of counts, with classifying factors educ (levels 1:5), orig (levels 1:7) and dest (levels 1:7).

## Fit the "UNIDIFF" mobility model across education levels, leaving out
## the uninformative subtable for dest == 7:
##
unidiff <- gnm(Freq ~ educ*orig + educ*dest +
                     Mult(Exp(educ), orig:dest), family = poisson,
                     data = yaish, subset = (dest != 7))
## Deviance should be 200.3, 116 d.f.
##
## Look at the multipliers of the orig:dest association:
ofInterest(unidiff) <- pickCoef(unidiff, "[.]educ")
coef(unidiff)
##
## Coefficients of interest:
## Mult(Exp(.), orig:dest).educ1 Mult(Exp(.), orig:dest).educ2
