Comprehensive update of midas available on SSC

[Ben A. Dwamena]

Thanks to Kit Baum, an updated midas package is now available through SSC archive. MIDAS (Meta-analytical Integration of Diagnostic Accuracy Studies) provides a comprehensive suite of commands for bivariate meta-analysis of diagnostic test accuracy data.

The package includes:

• 5 estimation methods: maximum likelihood (meglm), quasi-random simulated likelihood, Bayesian Metropolis-Hastings (bayesmh), Hamiltonian Monte Carlo (CmdStan), and integrated nested Laplace approximation (R-INLA)
• 8 exploratory commands: QUADAS/QUADAS-2 quality assessment, bivariate boxplots, chi-plots, Kendall concordance, assessment diagnostics, binomial sample size estimation, and exploratory forest plots
• 9 post-estimation commands: summary forest plots (4 plot types), SROC curves (regressional and bivariate), Fagan nomograms, likelihood ratio matrices, conditional probability plots, publication bias testing, Bayesian diagnostic plots, and clinical utility analysis (HSRUC)
• 2 heterogeneity investigation commands: stratified subgroup analysis and bivariate meta-regression with comparative SROC plots
• 5 data conversion utilities: simulation, ordinal-to-binary, continuous-to-binary, cluster-to-binary, and IPD-to-aggregate
• GUI dialogs for 29 subcommands

The package requires Stata 16+ and community-contributed bayesparallel, xsvmat and moremata packages. External software (R-INLA, CmdStan) is needed only for the inla and hmc estimators.

Hello Ben. Thanks for alerting us to the update. But I am having problems trying to download it from SSC.

First, I thought I checked to see which version I currently have:

. which midas
c:\ado\plus\m\midas.ado
*! version 2.00 December 21, 2008
*! version 1.00 August 15, 2007
*! Ben A. Dwamena: [email protected]

Then I tried updating via adoupdate:

. adoupdate midas, update
note: ado update updates community-contributed files; type update to check for updates to official Stata.

Checking status of specified packages:

  [128] midas at http://fmwww.bc.edu/RePEc/bocode/m:
        package has been updated on server

Packages to be updated are

  [128] midas        -- 'MIDAS': module for meta-analytical integration of diagnostic test accuracy studies

Installing updates ...

  [128] midas
        midas not updated; return code was 640
        Try updating midas again later, type ado update midas, update.  If that still does not work, type ado update midas, update
        verbose.


Cleaning up ... Done

Next, I tried this:

. ssc describe midas
r(640);

And finally, this:

. net describe http://repec.org/bocode/m/midas
package file too long
could not load midas.pkg from http://repec.org/bocode/m/
r(640);

Cheers,
Bruce

Midas is available both as the command level package and an optional dialog-based package
