What is decode Stata?
The decode command will convert a numeric variable to a string variable when that variable has a value label attached to it. Without a value label, Stata does not know what string you want to convert each different number into, and so is unable to decode the variable.

What is a byte variable in Stata?
Here we can see that the storage type is listed as “byte.” Byte indicates that the variable is stored as an integer between -127 and 100. The default data storage type for Stata is “float.” By inquiring with Stata using the help command, we see that the float variable type is much larger relative to. byte: .

decode() is a method specified in Strings in Python 2. This method is used to convert from one encoding scheme, in which argument string is encoded to the desired encoding scheme. It accepts the encoding of the encoding string to decode it and returns the original string.
What is the use of encode and decode in Stata?
The encode and decode commands in Stata allow you to convert string variables to numeric variables (encode) and numeric variables to string variables (decode). The encode command assigns a number to each different string, starting with the number 1 and continuing on (2, 3, 4, etc), while applying a value label to each number.
What is the special code for missing in Stata?
