Fitted semObject
Description
An object of class "sem" that represents the estimated model
parameters and standard errors.
Objects of this class have methods for the generic functions
print
, plot
and summary
.
Value
An object of class "sem" is a list containing the following components. Some parameters are only estimated for liner mixed regression models (and vice versa).
pseudo.y |
a matrix containing the pseudo samples of the interval-censored variable from each iteration step |
coef |
the estimated regression coefficients (fixed effects) |
ranef |
the estimated regression random effects |
sigmae |
estimated variance |
VaVoc |
estimated covariance matrix of the random effects |
se |
bootstrapped standard error of the coefficients |
ci |
bootstrapped 95% confidence interval of the coefficients |
lambda |
estimated lambda for the Box-Cox transformation |
bootstraps |
number of bootstrap iterations for the estimation of the standard errors |
r2 |
estimated coefficient of determination |
icc |
estimated interclass correlation coefficient |
adj.r2 |
estimated adjusted coefficient of determination |
formula |
|
transformation |
the specified transformation "log" for logarithmic and "bc" for Box-Cox |
n.classes |
the number of classes, the dependent variable is censored to |
conv.coef |
estimated coefficients for each iteration step of the SEM-algorithm |
conv.sigmae |
estimated variance |
conv.VaCov |
estimated covariance matrix of the random effects for each iteration step of the SEM-algorithm |
conv.lambda |
estimated lambda for the Box-Cox transformation for each iteration step of the SEM-algorithm |
b.lambda |
the number of burn-in iteration the SEM-algorithm used to estimate lambda |
m.lambda |
the number of additional iteration the SEM-algorithm used to estimate lambda |
burnin |
the number of burn-in iterations of the SEM-algorithm |
samples |
the number of additional iterations of the SEM-algorithm |
classes |
specified intervals |
