Therefore, the purpose of this paper is to provide novice researchers with a practical tutorial on how to estimate ESEM with a convenient online tool for Mplus. specified prior hypotheses, model-independent measures are generally Repeated Measures incorporated in software like SAS/STAT GLM [7], SPSS MANOVA [8].The deviation between the observed and expected frequencies characterizes the disagreement between the observation and the hypothesis of independence.
