On this Picostat.com statistics page, you will find information about the mdvis data set which pertains to mdvis. The mdvis data set is found in the COUNT R package. Try to load the mdvis data set in R by issuing the following command at the console data("mdvis"). This may load the data into a variable called mdvis. If R says the mdvis data set is not found, you can try installing the package by issuing this command install.packages("COUNT") and then attempt to reload the data with library("COUNT") followed by data("mdvis"). Perhaps strangley, if R gives you no output after entering a command, it means the command succeeded. If it succeeded you can see the data by typing mdvis at the command-line which should display the entire dataset.

If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the mdvis R data set. The size of this file is about 93,542 bytes.


mdvis

Description

Data from a subset of the German Socio-Economic Panel (SOEP). The subset was created by Rabe-Hesketh and Skrondal (2005). Only working women are included in these data. Beginning in 1997, German health reform in part entailed a 200 co-payment as well as limits in provider reimbursement. Patients were surveyed for the one year panel (1996) prior to and the one year panel (1998) after reform to assess whether the number of physician visits by patients declined - which was the goal of reform legislation. The response, or variable to be explained by the model, is numvisit, which indicates the number of patient visits to a physician's office during a three month period.

How To Import a Dataset
  1. Create a Picostat account or login with your existing picostat account (see above).
  2. Go to the dataset import page.
  3. Select a license for the dataset. The default is "No License" but allows Picostat to host a copy of the dataset as per the privacy policy. You may wish to uncheck the "Public" option if you do not wish to share your dataset with others. R Datasets that come by downloading R have a GNU General Public License v3.0 which may also be selected from the Picostat dropdown.
  4. Enter a title for the dataset
  5. Choose a dataset input methods. Available options include:
    • Random data - this populates your dataset with random numbers between 0 and 100. You can specify the number of rows and columns for the random dataset.
    • CSV, TSV or TXT file - you will have the option upload a file within the current file size limit and also specify the header and whether or not the dataset is a contingency table. With contingency tables, the first column becomes a label for the rows. Currently with Picostat, there is limited support for contingency tables. Choose "Yes" to the Header option if the first line of the data contains titles for the rows. Also choose the Separator for the dataset. A separator is what breaks the data up. In some cases, a comma would separate data values in a row. You will also have the option to add documentation in the form keyboarded text and also uploaded documentation attachments. You can also specify a license for the documentation.
    • Copy and Paste. This selection contains many of the same fields as importing a file with an additional textarea to copy and paste data to.
    • Empty dataset. Start with a blank dataset and manually add data with the Picostat dataset editor.
    • Excel file - Choose this option if you would like to convert your Excel spreadsheet to a Picostat dataset. With this selection, you will have the option to specify whether to use the first row in the Excel file as column names. If you would like to choose a specific sheet to use, you can also specify with entering its name in the text input.
    • sas7bdat file - SAS is a powerful statistical software package that has its own proprietary file format. Choose this option if you are importing a SAS file.
    • SPSS sav file - SPSS is a statistical package owned by IBM. You can import SPSS files by choosing this option.
  6. Choose whether or not the dataset contains a header. Some of the dataset input methods allow you to specify whether or not a Header exists on the file. Sometimes dataset files contain a Header as the first row which names the columns. If you choose "Yes" to this, the first row in the dataset will become column headers.
  7. You can also add documentation and specify a documentation license. This can be used to help explain your dataset to those unfamiliar with it.
  8. Choose whether or not to upload an supporting attachments.
  9. Pass the captcha. To prevent spam submissions, Picostat has a captcha which is used to prevent automated submissions by bots.
  10. Choose a privacy setting for the dataset. You can also specify whether or not the dataset is Public. If you uncheck this setting, only you and the Picostat administrator will be able to view the dataset.
  11. Submit the form. Once the form is validated, you will be redirected to the dataset homepage where you can choose to edit or perform statistical operations on the dataset.
