pinsearch: Specification Search for Partial Factorial Invariance

Automate specification search for identifying noninvariant items in factorial invariance analyses, as described in Yoon & Millsap (2007) <doi:10.1080/10705510701301677>. Models are specified in 'lavaan' syntax. Supports continuous indicators with loadings, intercepts, residuals (uniqueness), and residual covariances invariance, and ordered categorical indicators with loadings, thresholds, and residual covariances invariance.
