Hello,
Thank you for the question.
In looking at your example, the text states to use the linear regression command on a graphing device. As I researched this topic, I found that the linear regression command on a scientific calculator is “LinReg”. To get there, you click STAT, then CALC ….
Based on this information, the words linear regression will not appear on the screen, and you should transcribe contracted in UEB using a transcriber-defined font for the sans serif.
