Access model parameter estimates from an xpdb object.
get_prm(

)An xpose_data object from which the model output file data will be extracted.
The problem to be used, by default returns the last one for each file.
The subproblem to be used, by default returns the last one for each file.
The estimation method to be used, by default returns the last one for each file
The number of significant digits to be displayed.
Should diagonal OMEGA and SIGMA elements be transformed to standard deviation and off diagonal elements be transformed to correlations.
Logical, whether the 0 fixed off-diagonal elements should be removed from the output.
Logical, if FALSE messages are printed to the console.
A tibble for single problem/subprob or a named list for multiple problem|subprob.

#> Reporting transformed parameters:
#> For the OMEGA and SIGMA matrices, values are reported as standard deviations for the diagonal elements and as correlations for the off-diagonal elements. The relative standard errors (RSE) for OMEGA and SIGMA are reported on the approximate standard deviation scale (SE/variance estimate)/2. Use `transform = FALSE` to report untransformed parameters.
