“Ethnic and Racial Similarity in Developmental Process: A Study of Academic Achievement”, 1995 (; similar):
Correlation matrices were computed on academic achievement and family environment measures using longitudinal data on siblings. The 8 × 8 correlation matrices were computed on Hispanics, blacks, and whites separately.
When compared employing a LISREL method, the matrices were equal across these ethnic-racial groups. Hence, developmental processes influencing academic achievement may be similar in Hispanics, blacks, and whites.
A structural equation model with 4 free parameters was fitted successfully to a correlation matrix pooled across groups.
As a single structural equation model fitted all groups, the existence of minority-specific developmental processes was not supported.
