Description Usage Arguments Value See Also Examples
AnalysisCenter.2Party
and DataPartner.2Party
are used in conjuction
with PopMedNet to perform linear, logistic, or cox regression on data that has
been partitioned vertically between two data partners. The data partner
which holds the response variable(s) uses AnalysisCener.2Party
and the
other data partner uses DataPartner.2Party
. While both data partners
share information with each other in order to perform the regression, data is
kept secure and not shared, nor is any information shared that would allow
one data partner to reconstruct part of the other data partners data.
Final coefficients and other regression statistics are computed by the analysis
center and shared with the other data partner.

monitorFolder |
the folder where the directories |
msreqid |
a character string specifying the name of the Request ID as specified when creating the Distributed Regresion request on PopMedNet. Used for logging purposes only. |
blocksize |
the minimium size used to horizontally partition the data for data transfer between the two parties. |
tol |
the tolerance used to determine convergence in |
maxIterations |
the maximum number of iterations to perform
|
sleepTime |
the number of seconds to wait after writing the last file to disk before signalling the PMN Datamart Client that files are ready to be transferred. |
maxWaitingTime |
the number of seconds to wait to receive files before a transfer error is declared and the program halts execution. |

verbose |
logical value. If |
Returns an object of class
vdralinear
for linear
regression, vdralogistic
for logistic regression, or
