I am attempting to fit a regression model in STATA. My variables are are all continuous variables of type float.

HTML Code:
regress _gdp all_indexn_c 90_days consistent _incpc all_indexn_c#90_days
    
    all_indexn_c:  factor variables may not contain noninteger values
    r(452);
Array

How do I fix this issue? I don't have factor variables and I'd like to use float variables in the model.

Using STATA for the first time.
