        QUESTION

        De-identifying survival or flexsurvreg objects in R

        Asked 2022-Mar-29 at 11:01

        Please consider the following:

        I need to provide some R code syntax to analyse data with the flexsurv package. I am not allowed to receive/analyse directly or on-site. I am however allowed to receive the analysis results.


        Problem

        When we run the flexsurvreg() function on some data (here ovarian from the flexsurv package), the created object (here fitw) contains enough information to "re-create" or "back-engineer" the actual data. But then I would technically have access to the data I am not allowed to have.

        # Load package
        library("flexsurv")
        #> Loading required package: survival
        
        # Run flexsurvreg with data = ovarian
        fitw <- flexsurvreg(formula = Surv(futime, fustat) ~ factor(rx) + age,
                            data = ovarian, dist="weibull")
        
        # Look at first observation in ovarian
        ovarian[1, ]
        #>   futime fustat     age resid.ds rx ecog.ps
        #> 1     59      1 72.3315        2  1       1
        
        # With the following from the survival object, the data could be re-created
        fitw$data$Y[1, ]
        #>   time status  start   stop  time1  time2 
        #>     59      1      0     59     59    Inf
        fitw$data$m[1, ]
        #>   Surv(futime, fustat) factor(rx)     age (weights)
        #> 1                   59          1 72.3315         1
        
        

        Potential solution

        We could write the code so that it also sets all those data that might be used for this back-engineering to NA as follows:

        # Setting all survival object observation to NA
        fitw$data$Y <- NA
        fitw$data$m <- NA
        fitw$data$mml$scale <- NA
        fitw$data$mml$rate <- NA
        fitw$data$mml$mu <- NA
        

        Created on 2021-08-27 by the reprex package (v2.0.0)


        Question

        If I proceed as the above and set all these parameters to NA, could I then receive the fitw object (e.g. as an .RDS file) without ever being able to "back-engineer" the original data? Or is there any other way to share fitw without the attached data?

        Thanks!

        ANSWER

        Answered 2022-Mar-29 at 11:01

        Setting, e.g. fitw$data <- NULL will remove all the individual-level data from the fitted model object. Some of the output functions may not work with objects stripped of data however. In the current development version on github, printing the model object should work. Also summary and predict methods should work, as long as covariate values are supplied in newdata - omitting them won't work, since the default is to take the covariate values from the observed data.

        Install macOS-Security-and-Privacy-Guide

        The macOS installation application is code signed, which should be verified to make sure you received a legitimate copy, using the pkgutil --check-signature or codesign -dvv commands.
        Note Apple's AutoDMG installer does not appear to work across OS versions. If you want to build a 10.14 image, for example, the following steps must be performed on macOS 10.14!. To create a custom install image which can be restored to a Mac (using a USB-C cable and target disk mode, for example), use MagerValp/AutoDMG. Note The following instructions appear to work only on macOS versions before 10.13. Find InstallESD.dmg which is inside the installation application. Locate it in Terminal or with Finder, right click on the application bundle, select Show Package Contents and navigate to Contents > SharedSupport to find the file InstallESD.dmg. Verify file integrity by comparing its SHA-256 hash with others found in InstallESD_Hashes.csv or notpeter/apple-installer-checksums. To determine which macOS versions and builds originally shipped with or are available for a Mac, see HT204319.
        Accounts can be created and managed in System Preferences. On settled systems, it is generally easier to create a second admin account and then demote the first account. This avoids data migration. Newly installed systems can also just add a standard account.
