Description Usage Arguments Details Value Author(s) See Also Examples
Given a single RAM matrix, this function fits the model
and returns the output from either OpenMx
or
sem
.
1 2 |
returned.model |
The model of interest, in RAM format. (A column of "From" variables, "To" variables, the number of arrows, and the starting value.) |
dataset |
A correlation matrix. |
N |
The sample sized used to estimate the correlation matrix. |
openmx |
logical. Should |
fix.variances |
logical. Should variances be fixed to one? |
calc.se |
Should the standard errors be calculated? Defaults to no to speed up the DE algorithm. |
above ~~
Depending on which program is used to fit the data, either an OpenMx or an sem output.
