DataPlus Data
Manager Console
The data manager is opened by double-clicking on the DataPlus icon or a DataPlus file (filetype .d4d), which opens a blank manager.
Data files may be added to the DataPlus console by choosing "Open" from the "File" menu, or by importing text files using "Import Data..." . If text files are imported, they may be in the form of rows separated by returns and columns delimited by tabs, commas or white space. If white space delineation is used, you must be careful that the only white space is that between data fields. The tab-separated format is suggested. Data from from Excel or any other spreadsheet can be exported to a text file and then imported into DataPlus, as can a text file from any word processor. NOTE that there is a row of icons at the top of the window. Initially they are all dimmed. The icons will remain dimmed until there is data available for analysis.
When a text file is imported, DataPlus will first try to determine how the data is delineated. If it finds tabs in the first line, it assumes tab-delineated data. If it finds commas, then comma-delineation is assumed. If neither is found, then white-space delineation is used. If the first line of text contains non-numerical data, the fields are used as column headers for the following data. The first column containing non-numeric data is assumed to be a header title for the row.
Opening a
File:
From the "dataplus_docs/samples" folder, open the "smallseries" file.
The application should read the file and add a data
panel containing the data set.
The data panel shows the data set name and comment field (which may be
edited) along with
the number of records and data fields the set contains. The creation
date is when the file was first generated (or when it was created by
importation of a text file).
NOTE at this point, four icons are enabled, the Data Entry tool, the Matrix Sorting tool and the Formula tool. If there is only a single data set, such as there is in this case, the Multiple Regression tool is also enabled.
Analyzing the Data:
Depending upon the data analysis, it may be necessary to choose one or more data fields. The X, Y and Z field selection menus are initially set to "None". Not all data fields may show up in the menus; only those which are real numbers (float or double) or those which can be expressed as a real number (integer, enumerated variable) will be show. The type of data analysis enabled will depend upon how many axes are chosen. Choosing a single "X" axis enables the Distribution Analysis; choosing both an "X" and "Y" axis enables both the Linear Regression analysis and Polynomial Regression analysis. If all three axes are selected, the 3-D Plot is enabled. NOTE that if more than one data set is used (more on this later), all data sets must have the fields selected before an analysis is enabled.
At this time, choose the "X" and "Y" axes as shown.
The launch icons should now look like this:
NOTE! At this time, the only tools available are for Distribution Analysis, Linear Regression Analysis, and Multiple-Regression Analysis. More will be added here as they are completed.
