Statcalc epiinfo6/22/2023 ![]() The first two sections indicate how the various functions are accessed Menu Commands describes the functions in detail. In many cases, there are multiple ways to access a given functionality between, and even within, the canvas and Toolbar. The final section, Menu Commands, covers the tools accessed from the master menu including populating the canvas with gadgets, charts, and calculators, as well as loading and saving canvas and project data. Canvas discusses the requirements for functionality residing in the Dashboard itself. Navigation covers the Toolbar and Status Bar, located at the top and bottom, respectively, of the Visual Dashboard window. The requirements for this module are divided into three sections. While Visual Dashboard does not support programming for automated processing, the ability to update the analyses (with a single button-click) when new data becomes available, eliminates the need for it, in all but the most sophisticated use cases. Whereas the largely text-based output of Classic Analysis accumulates in a scrolling output page, with HTML anchors to facilitate navigation, the analytical tools in Visual Dashboard, known as "gadgets", are intended to be positioned on a canvas, like gauges on a dashboard, allowing the user to take in the status of the project in a single view. The Epi Info™ Visual Dashboard complements Classic Analysis with a more modern, graphically-oriented interface for configuring analytical tools and displaying their results. A user can create a sequence of commands representing a complex workflow in the Program Editor, save it as a file and execute it in batch mode, independently of the Classic Analysis GUI. The Explorer lists 46 commands organized into groups according to function: manipulation of datasets, individual variables, statistical analyses, defining new commands and generating output. Output is generated in HTML format and organized by a paging system that allows users to navigate forward and backward through the results using anchors embedded in the output of each command. ![]() The user can execute commands from the interactive, menu-driven Command Explorer or the text-based Program Editor. It is the core analytical component of Epi Info™ 7 and has remained largely unchanged in form and function through many versions and implementations of the package. Data to be analyzed may be collected using questionnaires created in Form Designer and populated using Enter or may be imported from external sources. The Epi Info™ 7 Classic Analysis (CA) module is used for the statistical analysis of data. The user can also return to Form Designer to edit the form and jump ahead to Classic Analysis or Visual Dashboard for data analysis, visualization, and reporting. Navigation buttons provide access to new, previous, next, first, and last records, as well as to their related tables, if any. In Enter, the cursor moves from field-to-field and then page-to-page, flagging invalid data according to the user-defined check code rules (if any) and then automatically saving data. The Find function allows records to be located that match values specified for any combination of variables on the form. Using the data table or tables constructed when the form was created and any subsequent check code added to the form, Enter can be used to enter new data, modify existing data, or search for records. The Enter module is the primary mechanism for data entry in Epi Info™ 7. A form can contain one or more pages, each corresponding to a database table to be populated using the Enter (data entry) module and processed by Classic Analysis or Visual Dashboard. Titles and supporting text can be added to the form data fields can be grouped, arranged, and aligned to enhance the form's readability and aesthetics. Starting with an empty canvas, the user can select data-entry fields including text fields, pull-down menus, check boxes, and radio buttons, as well as a graphic, calendar-driven fields for entering dates and auto-formatting fields for entering data such as phone numbers and times. Second, Check Code, specifies the needed input validation, skip patterns, automatic calculation of data, and intelligent field navigation. First, Form Layout supports project origination, the structure and relationship of forms, and the selection and positioning of data entry fields on pages, their properties and tab order. This module's functionality can be divided into two components. These steps are accomplished using Form Designer. As a suite of tools for collecting and analyzing- data, Epi Info™ 7 must support the creation of smart data entry forms that facilitate systematic data collection and perform data validation in real time.
