riclpm_text.Rd
Given a list of sets of variables sampled repeatedly over equal time intervals, create a Random Intercept Cross Lagged Panel Model (RI-CLPM) specification for lavaan.
riclpm_text(var_groups, constrain_over_waves = TRUE, constrain_ints = "free")
var_groups | A named list of vectors of variable names. See Details. |
---|---|
constrain_over_waves | Constrain regression coefficients, covariances, and residuals to be the same from wave to wave? Will not constrain variances and covariances of wave-1 latent residuals. |
constrain_ints | Constrain intercepts of manifest variables? Default is to free them. At the moment, passing other values is nonsense. |
Model text to be passed to a lavaan function.
The input is a named list of character vectors. The character
vectors should include the variable names as they appear in the data set.
The lists names will be used to create the variable name of the latent
random intercept term. For example, if the data has observed variables x
and y at waves 1-3, the var_groups
argument should be something like
list(x=c("x_t1", "x_t2", "x_t3"), y=c("y_t1", "y_t2", "y_t3"))
.
var_groups <- list( x=c("x_t1", "x_t2", "x_t3"), y=c("y_t1", "y_t2", "y_t3"), z=c("z_t1", "z_t2", "z_t3")) model_text <- riclpmr::riclpm_text(var_groups)
