Install Stata commands
- biasepi
- Second verion of Stata-package biasepi is ready. It includs three Stata commands (biascon, biasmis, and biasselect) to perform simple bias analysis, multidimensional bias analysis, multiple bias modelinging in epidemiological data. Combining the existing Stata commands, the package is capable to perform probabilitic bias analysis.
Type and run "ssc describe biasepi" in the Stata command window. You should be able to view and download the commands.
Be aware: you may have to remove the older version, if so, the following may help.
- PC: Go to C driver → ado → plus → b, remove biasepi, biasselect, biascon, biasmis
- Mac: Go to Folder → Library → Application support → Stata → Plus → b, remove biasepi, biasselect, biascon, biasmis
- episens
- In the Stata command window, type "search episens", you should be able find the information on command "episens" by Nicola Orsini et al.4
