Extract residuals from various psych objects
Residuals in the various psych functions are extracted and then may be "pretty" printed.
## S3 method for class 'psych' residuals(object,diag=TRUE,...) ## S3 method for class 'psych' resid(object,diag=TRUE,...)
object |
The object returned by a psych function. |
diag |
if FALSE, then convert the diagonal of the residuals to NA |
... |
Other parameters to be passed to residual (ignored but required by the generic function) |
Currently implemented for fa, principal, omega, irt.fa, and fa.extension.
residuals: a matrix of residual estimates
William Revelle
f3 <- fa(Thurstone,3) residuals(f3) sum(residuals(f3)^2) #include diagonal sum(residuals(f3,diag=FALSE)^2,na.rm=TRUE) #drop diagonal
