fit_uni_lcsm | R Documentation |
Fit univariate latent change score models.
fit_uni_lcsm( data, var, model, add = NULL, mimic = "Mplus", estimator = "MLR", missing = "FIML", return_lavaan_syntax = FALSE, ... )
data |
A data frame in "wide" format, i.e. one column for each measurement point and one row for each observation. |
var |
Vector, specifying the variable names of each measurement point sequentially. |
model |
List of model specifications (logical) for variables specified in
|
add |
String, lavaan syntax to be added to the model |
mimic |

return_lavaan_syntax |
Logical, if TRUE return the lavaan syntax used for simulating data. To make it look beautiful use the function cat. |
... |
Additional arguments to be passed to lavOptions. |
This function returns a lavaan class object.
