In this study, I conducted simulations to examine the properties of Maximum Likelihood Estimators (MLE) for parameters of the log-normal distribution. Investigated how the accuracy of estimation ...

1. a. Calculate the model parameters according to the data. b. Plot a graph showing the distribution of 𝒩 on x axis. 2. The true values of 𝜇 and 𝜎 are given. 𝜇 = 2, 𝜎 = 1.5. Add to the real ...

A transformational measurement model for structural equation modeling (SEM) of asymmetric non-normal data is proposed. This measurement model aligns with the expectation-maximization (EM) algorithm of ...
