Open Data Source — Text File (Data Import Wizard)

Context

For machine learning, BayesiaLab requires a dataset to be in a single data table. If data is not imported from a database, the data table needs to be in plain text format, e.g., a comma- or tab-delimited file.

The most common arrangement for the data table is:

Variable names are contained in the header row.
Columns contain the values of the variables.
Rows represent observations or records.

Binary files, Excel spreadsheets, SPSS, Stata, or SAS files must be converted into a text format, e.g., CSV, before importing them into BayesiaLab.

Usage

Select Menus > Data > Open Data Source, which prompts you to choose your data file from a local source. Upon selection, the Data Import Wizard launches.
