This article will introduce you to some of the most useful and easy to use features. A Stata date is simply a number, but with the %td format applied Stata will interpret that number as "number of days since January 1, 1960." You can then use that number in a variety of ways. May 28, 2014 · First, note that the logical operators are & (and) and | (or). Second, if you're asking whether Stata can interpret a string as a boolean value (e.g., as in Python), it can't. As an alternative, you can use the missing() function (or the synonym mi()) to mimic this behavior. For example, if y is a numeric variable and s is a string variable ... Stata has four different classes of operators: arithmetic, string, relational, and logical. Each type is discussed below. 13.2.1 Arithmetic operators. The arithmetic operators in Stata are + (addition), - (subtraction), * (multiplication), / (division), ^ (raise to a power), and the prefix - (negation).

If you guessed 4, you forgot either the precedence of algebraic operators or how Stata uses macros. `x' is replaced by -2 before Stata does anything with it, so it sees -2^2. But the power takes precedence over the minus sign, so this is the same as -(2^2), not (-2)^2. I'm a newcomer to Stata after using R for a long time. ... Macros constantly resulting in 'invalid name' ... And it seems you are not referencing your macros correctly. Stata datasets are rectangular arrays with n observations on m variables. Unlike packages that read one observation at a time, Stata keeps all data in memory, which is one reason why it is so fast. There’s a limit of 2,047 variables in Stata/IC, 32,767 in Stata/SE, and 120,000 in Stata/MP. Stata datasets are rectangular arrays with n observations on m variables.

This entry concerns advanced issues not previously Macros A Stata macro is different to an Excel macro. In Excel, a macro is like a recording of repeated actions which is then stored as a mini-program that can be easily run – this is what a do file is in Stata. Macros in Stata are the equivalent of variables in other programming languages.
  • The danger of using `a' 2 rather than (`a') 2 did not exist in Stata 4 and earlier; it does exist in all modern Statas. Older Statas took −2 2 to be (−2) 2 or 4, and so coding `a' 2 was perfectly safe. Stata has four different classes of operators: arithmetic, string, relational, and logical. Each type is discussed below. 13.2.1 Arithmetic operators.

first element of macro ... We are creating a local macro. This is a piece of text Stata saves in the memory until the end of the dofile. ... is Stata’s OR operator ... Hi there, Suppose I have the following macro %MACRO MacroA(varA, varB); I would like to create a new dataset that should be named varA_varB. For example, if varA is hello and varB is world, the datasource would be hello_world. I tried &varA + "_" &varB in my macro code, but SAS doesn't like tha... Note that the values for assigning centuries are based on my knowledge of my “data.” First of all, we extract all the digits for year. We use the "$" operator to indicate that the search is from the end of the string. We then turn the string variable into a numeric variable using Stata’s function "real". Jun 20, 2017 · This will go over the basic syntax and information about foreach and forvalues loops in Stata, as well as how to use them with levelsof.

For example, if varA is hello and varB is world, the datasource would be hello_world. I tried &varA + "_" &varB in my macro code, but SAS doesn't like tha... A macro in Stata begins with the word “global” or “local”.   The command global tells Stata to store everything in the command line in its memory until you exit Stata.   If you open another data set before exiting, the global macro will still be in memory.

A prefix operator is an operator that is applied to the variable, constant, function, or parenthetic expression that immediately follows it. The plus sign (+) and minus sign (-) can be used as prefix operators. The word NOT and its equivalent symbols are also prefix operators. The simplest assignment operator is colon-equals (:=), which stores the result of an expression in a variable. For a description of what the other operators do, see their related entries in this table. For example, Var //= 2 performs floor division to divide Var by 2, then stores the result back in Var. Jun 20, 2017 · This will go over the basic syntax and information about foreach and forvalues loops in Stata, as well as how to use them with levelsof. Operators in macro expressions are a subset of those in the DATA step (Macro Language Operators). However, in macro, there is no MAX or MIN operator, and macro does not recognize IN or ':', as does the DATA step. The order in which operations are performed when an expression is evaluated is the same in the macro language as in the DATA step. It chapter two google docsApr 17, 2019 · you can replace the values of same variable in stata by using the replace command of stata. Skip navigation ... STATA(7) generate replace, logical operator and if statement - Duration: 15:23 ... Stata datasets are rectangular arrays with n observations on m variables.

There’s a limit of 2,047 variables in Stata/IC, 32,767 in Stata/SE, and 120,000 in Stata/MP. So before Stata introduced ++ as a operator Stata tokenized local c+ as a command -local-, a name -c- and text "+" with the effect that the local macro -c- was set to contain "+" as its contents. Similarly with local c++ and "++" as its contents.

SAS also provides several other operators that are used only with certain SAS statements. The WHERE statement uses a special group of SAS operators, valid only when used with WHERE expressions. For a discussion of these operators, see WHERE-Expression Processing. The _NEW_ operator is used to create an instance of a DATA step component object.

Substitute objects. In Stata, any part of the code can be substituted with macros. There are no macros in R: you cannot directly substitute some part of your code by enclosing it in special quotes. An Introduction to Mata . Mata is a matrix language built into Stata, similar in many ways to R, Matlab or GAUSS. It does have some unique and intriguing features however. One is that it is a compiled language rather than interpreted, which improves performance.

A Stata macro is a box you put text in. You then use what's in the box in subsequent commands. (The real trick is getting a single command to run multiple times with a different bit of text in the box each time--we'll get there). The macros we'll use are "local" macros.
