Factor variables may not contain noninteger values

[keval shah]

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

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);

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.

What is the # doing in your command? The way you use it implies that the variables before and after the pound sign should be treated as categorical and you are interacting them. Both variables should be preceded by c. If you want them treated as continuous. See

help fvvarlist

for more details.

Also, 90_days is not a legitimate variable name. The first character of a variable name must be a letter or an underscore. Further, starting variable names with an underscore is discouraged because all of Stata’s built-in variables begin with an underscore.
