We provide functions to compute confidence intervals (CIs) for a well-defined nonlinear function of the model parameters (e.g., product of k coefficients) in single--level and multilevel structural equation models.
*'medci' function output structure is changed. For each 'type', it produces a 'list' of '(1-alpha/2)% CI', 'Estimate', and 'SE'. See help(ci) for more information.
*Two functions 'pMC' and 'qMC' are added.
*for medci(), type=‘prodclin’ is replaced with ‘dop’.
*New 'ci' function produces CIs for any well-defined function of parameter estimates in an SEM and MSEM using the Monte Carlo or asymptotic normal theory with the multivariate delta standard error method.
