This tool is designed to analyze up to 5 Fraud Detection Questions integrated into a survey, focusing on potential fraudulent participants to clean the survey dataset from potential fraud. Fraud Detection Questions and further information available at <https://surveydefense.org>.

Generate programmable surveys using markdown and R code chunks. Surveys
    are composed of two files: a survey.qmd 'Quarto' file defining the
    survey content (pages, questions, etc), and an app.R file defining a
    'shiny' app with global settings (libraries, database configuration,
    etc.) and server configuration options (e.g., conditional skipping /
    display, etc.). Survey data collected from respondents is stored in a
    'PostgreSQL' database. Features include controls for conditional skip
    logic (skip to a page based on an answer to a question), conditional
    display logic (display a question based on an answer to a question), a
    customizable progress bar, and a wide variety of question types,
    including multiple choice (single choice and multiple choices),
    select, text, numeric, multiple choice buttons, text area, and dates.
    Because the surveys render into a 'shiny' app, designers can also
    leverage the reactive capabilities of 'shiny' to create dynamic and
    interactive surveys.

Visualize and tabulate single-choice, multiple-choice, matrix-style questions from survey data. 
    Includes ability to group cross-tabulations, frequency distributions, and plots by categorical variables and 
    to integrate survey weights. Ideal for quickly uncovering descriptive patterns in survey data.

A tool for computing network representations of attitudes,
  extracted from tabular data such as sociological surveys. Development of
  surveygraph software and training materials was initially funded by the
  European Union under the ERC Proof-of-concept programme (ERC,
  Attitude-Maps-4-All, project number: 101069264). Views and opinions expressed
  are however those of the author(s) only and do not necessarily reflect those
