thurstone {eba} | R Documentation |
Fits a Thurstone-Mosteller model (Case V) by maximum likelihood.
thurstone(M)
M |
a square matrix or a data frame consisting of absolute choice frequencies; row stimuli are chosen over column stimuli |
thurstone
provides a front end for glm
.
See Critchlow & Fligner (1991) for more details.
estimate |
a vector of parameter estimates (scale values), first element is set to zero |
goodness.of.fit |
the goodness of fit statistic including the likelihood ratio fitted vs. saturated model (-2logL), the degrees of freedom, and the p-value of the corresponding chi-square distribution |
tm.glm |
the output from a call to glm |
