Text output

Compiler Output: The output from compiling the model.cpp file, the C++ language source program that results from building a model in NLME or in Phoenix Modeling Language text. Any errors in compilation will be noted here. If there are any errors, the model fitting process will not run.

Core Output: A text version of output from the running the fitting process. Includes fitted parameter values, eigenvalues, condition number of the matrix of partial derivatives (square root of the ratio of the largest to the smallest eigenvalue), log likelihoods, post hoc estimates, shrinkage values for each epsilon, and a table of goodness-of-fit items (data values, individual and population predictions and residuals, etc.).

Core Status: A text version that lists the minimization process, the minimization engine used, as well as a summary of the Optimal Parameter Estimates and eta shrinkage statistics. (See the Omega worksheet description for information on shrinkage computations.)

Model Text: The PML (Phoenix Modeling Language) code that is generated as the model is specified, plus the column definitions generated when a dataset is mapped.

Remote log: If the model was executed remotely, the log can be reviewed here.

Settings: The settings sent into the compiler and runtime engine. Includes mappings and model code.

Status Window Text: Lists the text that appeared in the Status Window during execution.

Stepwise Text: Stepwise Run Mode only. Explains decision on which covariates to add or subtract in the next step of the covariate search.

Warnings and Errors: If any runtime errors are encountered, they are written to this file.

Additional output

Additional output consists of files that are not be viewed within Phoenix but can be exported and viewed in other software. Additional output file remain part of a Phoenix project but they cannot be used as input to any Phoenix object downstream. Often files created as additional output have the potential to be very large (e.g., simulation). If the user wishes to export and import back these files into Phoenix, caution should be taken to ensure sufficient memory resources.

BootSubj(B).csv: Created for bootstrap mode run. Table showing the subjects that were randomly included in each sample as well as the numbers of tries for those samples.

dmp.txt: These files are created for population models with the Simple mode. The intention is for R users to be able to post-process these files. The dmp.txt files can be loaded into R and they can be used for processing of Phoenix NLME results in R. Individual eta shrinkage statistics are listed at the end of the file. See the Omega worksheet description for information on shrinkage computations.

Rawout.csv: These files list the estimates of Thetas, Omega, and Log-Likelihood for each executed sample.

Rawsimout.csv: These files list the simulation estimates for each executed sample. When running simulation in an individual model, one Rawsimout.csv file is generated for each subject.

Rawsimtbl01.csv–Rawsimtbl05.csv: Optional tables created by the Predictive Check mode, if Tables are requested under the Tables tab and the size is too large to load into Phoenix. The content depends on what the user enters.

Additional Simulation output

Optionally, if a user selects a folder in which to copy simulation results then csv files are saved to that directory. This is only available for population models in Simulation run mode.

Predout.csv: The same as the PredCheckAll worksheet described above (see “Worksheet output”).

simtbl01.csv–simtbl05.csv: Optional tables created by the Simulation mode, if Add Sim Table is used on the Options tab. The content depends on what the user enters.
