Once natural strata have been organized, the estimation of impact follows statistical procedures known since the 1950s for analysis of stratified case--control design (Cochran 1950; Mantel and Haenszel 1959).
Mantel (1963) proposed a statistic that is an extension of the standard Mantel-Haenszel (MH) procedure (Mantel & Haenszel, 1959), and it is often used as the gold standard for detecting items with differential functioning.
Two different methods were used: item response theory (IRT), following Raju's method of determining DIF (Oshima & Morris, 2008); and the Mantel-Haenszel method (Mantel & Haenszel, 1959).
Para ello se utilizo el metodo estadistico de Mantel Haenszel, ya que se aplica en estudios con muestras pequenas y escasos eventos.
Se aplicaron tres metodos para detectar DIF: el primero, diferencia entre los centros de las dificultades, el segundo, diferencia entre los extremos mas proximos de los intervalos de las dificultades y finalmente, la prueba estadistica de Mantel y Haenszel.

Os calculos da analise de variancia foram executados com apoio do procedimento (media e desvio padrao) Glimmix e a tabela de contingencia e o teste de qui-quadrado de Mantel Haenszel com apoio do procedimento FREQ, ambos do sistema StatisticalAnalysis System [24] (SAS).
Mantel and Haenszel (1959) proposed a very similar test and introduced an estimator for a common odds ratio.
This was the beginning of a lasting and fructiferous association of Haenszel with the Cali Registry recognized by Universidad del Valle, which gave him the title of Doctor Honoris Causa.
We applied three basic extension of Chi square that is Pearson's Chi square likelihood ratio and Mantel Haenszel statistics (Wrigley 1985; Agresti 1990; Nachmias and Nachmias 1996).
