DCPOtools includes functions to help preparing panel data for Dynamic Comparative Publicion Opinion (DCPO) analyses.
The study of comparative public opinion has been hampered by data that is sparse, that is, unavailable for many countries and years; incomparable, i.e., ostensibly addressing the same issue but generated by different survey items; or, most often, both. DCPO for estimating latent public opinion from cross-national survey data to maximize the information gleaned from available sources, overcome issues of missing and incomparable data, and allow comparativists to examine the dynamics of public opinion across countries.
For a detailed description, see the working paper here.
The method is associated with an R package, DCPO, for users' convenience to apply the method.
However, there are special requirements for the data format to conduct DCPO, and this is where the DCPOtools can provide help.
DCPOtools requires the package gesisdata to be successfully installed.
Before gesisdata is released in CRAN, users should first install it before installing DCPOtools with the follow commands:
remotes::install_github("fsolt/gesisdata")Then, the DCPOtools can be installed with the following commands:
remotes::install_github("fsolt/DCPOtools")Please be aware that DCPOtools is only for data preparation.
To apply DCPO, one should install the DCPO package separately.
See the instruction of the DCPO package here.
