Downloading Siena



Executable programs

  • The official releases of SIENA are version 4: the R package , and version 3: part of the StOCNET program suite.
    The R package RSiena can be installed in the regular way within R. However, in view of the frequent updates, it may be advisable to download the most recent version of RSiena from R-Forge.
    The most recent official release of version 3 can be downloaded from the StOCNET website.
  • RSienaTest_1.0.12.204.zip, the 29-02-2012 version of RSienaTest (installer for Windows), which currently is not available on R-Forge. I will look into this.
    Windows users can use this in R to "install from local zip file".
  • For the meta-analysis of several data sets analyzed by SIENA 3, which also may be called a poor-man's multilevel network analysis (where the poverty refers to the lack of a random coefficient multilevel model), the program SIENA08, which can be downloaded here, can be used.
    This carries out the analysis according to Snijders and Baerveldt (2003), extended with applications of Fisher's method of combining independent tests.
    In RSiena, this is carried out by the function siena08 which is available and documented in the regular way.
  • In Steglich, C.E.G., Snijders, T.A.B. and Pearson, M. : Dynamic Networks and Behavior: Separating Selection from Influence (Sociological Methodology, 2010), for users of SIENA 3, one of the techniques is the simulation of values of network autocorrelation statistics (Moran"s I and Geary`s c) using Siena05 according to hybrid models. This requires the composition of a new .mo file from two earlier existing .mo files. This can be done conveniently using the program S_Merge, which can be downloaded here.
  • File siena_l_exe_318_7.zip contains the executable files for Siena 3.181 (new beta version, April 8, 2010).
    Some minor (non-serious) bugs are corrected.
    (The version of January 18 did not work properly.)
  • File siena_l_exe_317y.zip contains the executable files for Siena 3.17y (new beta version, September 18, 2009).
    Some minor (non-serious) bugs are corrected.
  • File siena_l_025ae_exe.zip contains the executable files for Siena 3.17w (new beta version, May 26, 2009).
    This corrects a bug which made it impossible to estimate more than one endowment effect; it corrects a bug which occurred in the multi-project option when it makes use of unconditional estimation (which always is the case for networks and behavior); and the balance effect now is multiplied by (n-2), to bring the value of this parameter more in line with other parameters (mainly for larger networks) - this change is documented in the manual.
  • File siena_l_025ac_exe.zip contains the executable files for Siena 3.17v (new beta version, May 22, 2009).
    The degree - popularity (sqrt, for nondirected networks) and indegree - popularity (sqrt) effects as well as the raw (not sqrt) out-indegree assortativity effect had serious errors (for the in/degree-popularity effect, only in Siena versions 3.15 to 3.17u). Also the out-indegree assortativity, in-out degree assortativity, and in-indegree assortativity effects had errors. All these effects have been corrected. I thank Krists Boitmanis for bringing these errors to my attention. Further, improvements were made for handling structurally determined values that change between waves; for calculation of network autocorrelation statistics, structurally determined values now are excluded (which is an improvement for some cases but not always); and changing actor covariates with some missing values now are imputed by carrying forward the last observed values.
  • File siena_l_025z_exe.zip contains the executable files for Siena 3.17t (new beta version, April 23, 2009).
    Some recovery work was done, and a few extra effects added, for the ERGM case.
  • File siena_l_025w_exe.zip contains the executable files for Siena 3.17s (new beta version, March 22, 2009).
    There was an error in the calculation of the transitive triplets effect (it was combined with the transitive mediated triplets effect) and also in the standard errors of the endowment effects. These were corrected, along with some smaller changes.
    Further, the treatment of the case that there are structurally determined values which change over time has been improved. An error for this case (for calculating distances / rate function parameters) had been corrected in version 3.17i, but then due to an undesirable oversight resurfaced in versions 3.17n - 3.17q. The error was corrected again, and some improvements were added, in version 3.17s. The improvements are documented in the new manual at the end of Section 5.1.1.
  • File siena_l_025t_exe.zip contains the executable files for Siena 3.17p (new beta version, February 10, 2009).
    The degree-related effects have been extended and renamed in accordance with the new tutorial. Further there was a bug in the simulation program for the case that 1 simulation was requested; this bug is corrected now.
  • Siena 3.17n (December 1, 2008) incorporates just a few small changes. These executables were compiled using Lazarus (again), and thereby allow larger networks than the few preceding series of executables.
    Unfortunately, the bug repair of version 3.17i was missed here, and was included only again from version 3.17 r.
  • Siena 3.17i (October 20, 2008) repaired a bug that occurred for some data sets with changes in structurally fixed values (codes 10 or 11 for the tie variables).
  • Siena 3.17g (September 8, 2008) contains the new multi-group option (combination of several projects into one project, as an alternative to working with blocks of structural zeros) and has implemented endowment effects for dependent behavior variables. It supersedes versions 3.17e and 3.17g which did the same and had some minor errors. In addition, there are three extra behavior effects compared to 3.17c (see the manual, Section 15.2.1).
  • Siena 3.17c (June 30, 2008) contains some new effects:
    • Doubly achieved distances two: the number of pairs (i,j) of actors who are not directly tied, and between whom there are at least two two-paths i => h => j;
    • For dyadic covariates W, three types of mixed transitive closure. Denoting the network by X, these mixed closures are of types WW=>X, WX=>X, and XW=>X.
    See the manual (Chapter 15) for further explanation.
    Further two bugs were repaired. One bug led to wrong labelling of statistics in case more than one dependent behavioral variable was specified.
    The other repaired bug occured only when estimating models under the option that more output is requested as indicated in Section 12 of the manual, item 2 (i.e., when 10 is added to the Model Code).
  • Siena 3.17a (April 8, 2008) discovers automatically when actor variables are constant within waves or within connected components separated by structural zeros, and then will allow any interactions for such variables (which was previously not allowed in the ERGM case). Further, some new effects were added (betweenness for nondirected networks, and covariate values of indirect ties).
  • executable files for Siena 3.15 (new beta version, February 6, 2008).
    This fixes an error which occurred in Siena01 when there were more dyadic covariates than actor covariates. Also it now is discovered automatically if no ties are terminated (only formed), or no ties are formed (only terminated), and then the model respects these constraints. Further, some new effects are added (assortative matching and interactions).
The new SIENA 3 versions also incorporate some bug repairs, see the news page.
The error in the estimation of ERGM models with structurally determined values is repaired only for Model Code = 11 or 15. This is much less efficient than Model Code 14, which is the normal default.

In general, when you have downloaded a new version of Siena 3, working with this new version will require that you run Siena01 again on your project files.
