+\title{Compute rasch person-item residuals}
+\usage{
+res_ij(thetahat_i, delta_hat_j, res, beta = 0)
+}
+\arguments{
+\item{thetahat_i}{Person parameter estimate for person i}
+
+\item{delta_hat_j}{Item threshold parameter estimates for item j}
+
+\item{res}{Response of person i to item j}
+
+\item{beta}{Estimated latent mean difference between groups, can be ignored}
+}
+\value{
+A single scalar equal to the residual for person i on item j
+}
+\description{
+This function computes person-item residuals for rasch family adjacent-categories models
+like the Rasch model or the PCM
