Threshold assessment

[Maxime St-Onge]

Hi,   I am trying to determine a cut-off point or threshold for two continuous variables.  I was told that a segmental regression analysis was the proper operation to perform.  Is there any other operations that can be done (beside percentile, etc.) to precisely pin point the inflexion?  If not, does anybody have a good reference on how to perform segmental regression analysis (SPSS)?   Thanks,   Maxime St-Onge   Post messages to [EMAIL PROTECTED]  To (un)subscribe, send any message to sportscience-(un)[EMAIL PROTECTED] View all messages at http://groups.yahoo.com/group/sportscience/.
