symSEM
Symbolic Computation for Structural Equation Models
The symSEM package uses the caracas package, which depends on the SymPy library, for the symbolic computations.
The stable version can be installed from CRAN by:
install.packages("symSEM")
The developmental version can be installed from GitHub by: ```
Install remotes package if it has not been installed yet
install.packages("remotes")
remotes::install_github("mikewlcheung/symsem") ```
Example
Compute a symbolic model-implied covariance and correlation matrices
``` library(symSEM)
A regression model
model <- "y ~ b1x1 + b2x2 ## Covariance between x1 and x2 x1 ~~ x2 ## Means y ~ b01 x1 ~ m11 x2 ~ m2*1"
Convert it into a RAM speculation
RAM <- metaSEM::lavaan2RAM(model)
Implied covariance matrix and mean structure
impliedS(RAM, corr=FALSE)
Implied correlation matrix
impliedS(RAM, corr=TRUE) ```
