Hello, Apologies if this is a basic question, but I am struggling to fully understand the Advanced Adviser Options when Creating a Data Source Using the Data Source Wizard in SAS Enterprise Miner. I have looked at the manual here: https://documentation.sas.com/doc/en/emref/14.3/p0ldp4l9cnob3gn1dytmimkunaa6.htm#p1ei4x1wp5rxknn0zgx557te8nru but would very much appreciate some clarification. Detect Class Levels — specifies whether the number of class levels is determined for each variable. Does this mean that because the software has not yet decided whether a given variable is numerical or categorical etc. it entertains the possibility of it being the latter? For example, even if it were provided with numerical values, the software would count the frequency of unique numbers; if the number 5 appeared 10 times in the variable, then the count for "category" 5 would be 10? Class Levels Count Threshold — specifies the maximum number of class levels for each variable. When the Detect Class Levels property is set to Yes, if there are more class levels than the value specified here, the variable is considered an interval variable. Valid values are positive integers greater than or equal to 2. I'm assuming this the part where the software is deciding whether the variable is categorical or numeric. So, if Detect class levels is "yes" and the class levels count threshold is 20, then a "numeric" variable with no more than 20 distinct "classes" would be considered a factor, whilst for >20 distinct classes it would be considered numeric? Also I cannot really see the distinction between the above settings and others which are available, namely: Reject Vars with Excessive Class Values and Reject Levels Count Threshold Thank you for your help!
