     Happy New Year!
     
     I'm posting for a colleague with a statistics question:
     
     The basic question is this... If you overlay two histograms and do a 
     K/S statistical analysis, it will give you a % probability that the 
     curves are different.  This has been used to show that binding in the 
     experiment has occurred.  If you want to show that binding has NOT 
     occurred or has been blocked, at what level of probability can you say 
     that the two curves are NOT different?
     
     How do you prove both that binding has occurred (two curves are 
     different) and that you have now been able to block binding (two 
     curves are not different)?
     
     Are people out there using other statistics to show this?  What type 
     of numbers show statistical significance in your results?
     
     I haven't seen much in publications about interpretation of data like 
     this.  Feel free to reply directly to me or post back to the group.
     
     Thanks in advance for the help!
