T am trying to replicate a regression using Gauss and I keep on getting "G0152: Variable not initialized". How can I fix this problem?
If you use a variable that has not yet been mentioned in your GAUSS program, or GAUSS session, for example:
a = b;
GAUSS will return the error "Undefined symbol : 'b'. This means that GAUSS has not seen a reference to the variable, 'b' in this case, before the code attempted to use it.
The error Variable not initialized occurs when the GAUSS program declares a variable--essentially promising that it will be assigned to by some other code, but the variable is never assigned to. Here is a simple example that will cause the error:
//Remove all variables new; //Declare that 'a' will be a sparse matrix //to be filled in later sparse matrix a; //Attempt to use the value of 'a' //before it was set b = a * 4;
The error message should tell you the line on which the uninitialized variable is being used.
