Stata Package Installation
Overview
The package installation module provides a convenient way to install Stata packages from the Statistical Software Components (SSC) archive. It supports automated package installation within Stata-MCP workflows, making it easy to extend Stata's functionality programmatically.
Key Features
SSC Archive Integration
Directly installs packages from the Boston College Statistical Software Components archive:
- Automatic Installation: Installs packages with a single command
- Dependency Handling: Stata's package manager handles dependencies automatically
- Version Management: Supports updating existing packages with the
replaceoption
Cross-Platform Support
Works on all supported operating systems:
- Windows: Full support through Stata's batch execution mode
- macOS: Native support through Stata CLI
- Linux: Native support through Stata CLI
Installation Verification
The module provides built-in verification to ensure successful installation:
- Checks for installation success messages
- Handles already-installed packages gracefully
- Returns clear status messages for troubleshooting
Use Cases
- Automated Setup: Install required packages in automated research workflows
- Environment Initialization: Prepare Stata environments with necessary packages
- Missing Package Recovery: Automatically install packages when commands are not found
- CI/CD Pipelines: Set up consistent Stata environments in automated testing
How It Works
- Command Construction: Builds the appropriate
ssc install {package}command - Stata Execution: Sends the installation command to Stata CLI
- Result Verification: Checks the output for success indicators
- Status Reporting: Returns the installation status and any messages
Installation Behavior
By default, the installer uses the replace option:
- New Packages: Installs the package for the first time
- Existing Packages: Replaces with the latest version from SSC
- Up-to-Date Packages: Skips installation if already at the latest version
Common Packages
Some frequently installed packages include:
estout: Regression and estimation tablesoutreg2: Alternative regression table outputcoefplot: Coefficient plotstabout: Export tables to various formatsgraphexport: Enhanced graph export options
Error Handling
The module handles common installation scenarios:
- Package not found on SSC
- Network connectivity issues
- File permission problems
- Stata license limitations
Example Workflow
// Install a package
ssc install estout
// The module handles:
// 1. Downloading from SSC
// 2. Installing to your Stata ado directory
// 3. Setting up help files
// 4. Verifying installation
Notes
- Requires internet connection for SSC access
- Installation speed depends on package size and network connection
- Some packages may have additional system requirements
- Always verify package functionality after installation
