ipacheck

Overview

ipacheck is a Stata package for running high-frequency checks on research data at Innovations for Poverty Action, including:

• ipacheckcomplete - verifies that all surveys are completed.
• ipacheckdups - identifies possible duplicate observations.
• ipacheckconsent - verifies that all surveys have consent.
• ipachecknomiss - verifies that certain variables have no missing values.
• ipacheckfollowup - verifies consistency of data between rounds of data collection (e.g. baseline and follow up).
• ipachecklogic - asserts that skip patterns are followed.
• ipacheckallmiss - identifies variables who contain only missing values.
• ipacheckconstraints - asserts that hard and soft constraints are followed.
• ipacheckspecify - lists all values specified for variables with an 'other' category for possible recoding.
• ipacheckdates - verifies consistency of date variables.
• ipacheckoutliers - identifies possible outliers in numeric variables.
• ipatracksummary - lists number of surveys completed by date.
• progreport - lists surveys completed against sample/tracking list filtered by a variable.
• ipatrackversions- lists number of surveys by date and version.
• ipacheckenum - aggregates data by enumerator to assess performance.
• ipacheckresearch - produces one- and two-way summaries of research variables.
• ipacheckids - creates a formatted output sheet to compare differences between duplicate observations.

ipacheck comes with a folder structure for your project including a master do-file and Excel-based inputs sheets. Results of checks can be exported as nicely formatted Excel spreadsheets for distribution among field teams.

Installation

* ipacheck may be installed directly from GitHub
net install ipacheck, from("https://raw.githubusercontent.com/PovertyAction/high-frequency-checks/master/ado") replace 

* after initial installation ipacheck can be updated at any time via
ipacheck update

* to start a new project with folder structure and input files
ipacheck new, surveys("SURVEY_NAME_1") folder("path/to/project")

* when starting a new project with multiple surveys, you can choose to use the subfolders option to create subfolders for each survey
ipacheck new, surveys("SURVEY_NAME_1" "SURVEY_NAME_2") folder("path/to/project") subfolders

* to obtain fresh copies of the master do-file and Excel inputs without creating the folder structure
ipacheck new, files

* to verify you have the latest versions of the commands
ipacheck version
