Detect variable type

The system will ask you to detect variable type when you load a non-mtx file or a database table to build a new model.

Detection range

To make sure that you input variables with correct types, you can check “Detect variable types now”. For a large file, you can check “Do not detect (Can be detected later via "Detect variable data type" option)” to perform detection in “Detect variable data type” menu.

By checking “Do not detect (Can be detected later via "Detect variable data type" option)”, data will be imported with default variable type “Categorical variable”. Later you need to perform detection in “Detect variable data type” menu on the main screen, or set the type for each variable manually. You’ll get an error report during model building process if you skip the detection or set wrong variable types.

Default configuration

If you check an option, the choice will be observed the next time you open the “Load data” window. You can change the configuration in Tools ->Configuration, as shown in the following example:
