WebMar 29, 2012 · Let’s see two different methods of checking if string is empty or not: Method #1 : Using Len () Using Len () is the most generic method to check for zero-length string. Even though it ignores the fact that a string with just spaces also should be practically considered as an empty string even its non-zero. WebMar 14, 2016 · Multicollinearity doesn’t care if it’s a categorical variable or an integer variable. There is nothing special about categorical variables. Convert your categorical variables into binary, and treat them as all other variables. I assume your concern would be categorical variables must be correlated to each other and it's a valid concern.
