Raff Regession Channel/Linear Regression

[theking2000]

Does anyone know if under "basic studies,"a Raff Regression Channel has been added to the linear regression? I was wondering what kind of channel that was which appears on the linear regression. Also, as a side note, does anyone know if we have access to the "large block ratio?" Thanks.

Raff Regression is not available at this time. The channel can be either a Standard Error or Standard Deviation depending on the option selected in Edit Studies
