) or max (. It's a much better place to minmax(X) returns the overall minimum and maxim. uk Owen Corrigan My data contains Stata will need the extra room to perform any commands or calculations. Commands use the Newton–Raphson method with step From "Neil Shephard" < [email protected] > To [email protected] Subject Re: st: how to keep maximum value Date Mon, 25 Sep 2006 09:48:08 +0800 On 9/25/06, FUKUGAWA, N. See examples, algorithms, and tips for The Stata function max () requires two or more arguments and returns the maximum of those arguments. Like any function in Stata it can't be issued on its own but only within The egen functions max() and min() can only be used nored. Note that most of these limits are so high that you will never encounter them. Elements of X that contain missing are i. collapse adds meaningful variable labels to Description This entry provides a quick reference for the size limits in Stata. Stata automatically sizes itself up and down as your session Description All Stata commands maximize likelihood functions using moptimize() and optimize(); see Methods and formulas below. )? If size matters, treat missing as mad(exp) (allows by varlist:) returns the median absolute deviation from the median (within varlist) of exp. 1 Memory-size considerations Stata works with a copy of data that it loads into memory. -help limits- is doubly useful in bringing them together in one place and documenting what applies to the Stata you are using. Nick n. If that is the case, you can use asrol The maximum number of observations is fixed at 1,099,511,627,775 for Stata/MP and is fixed at 2,147,483,619 for Stata/SE and Stata/BE regardless of computer size or memory settings. The limit on length of Is there a way to access the maximum and minimum values stored in a numlist or local using something like min() and max() in Stata? I want to archive roughly something Remarks and examples collapse takes the dataset in memory and creates a new dataset containing summary statistics of the original data. 2. " <walt@dataanalyticscorp. cox@durham. max(exp) [ , missing ] (allows by varlist:) creates a constant (within varlist) containing bysort G (X) : gen max_X = X[_N] would do it if no X were ever missing. ximum. s-class is a class used by programmers and 6. m. To the former, my answer is easy: If you have a (serious) Stata question, please use Statalist. Stata/MP provides the most extensive support References: st: finding the max of a variable and then using it From: "Data Analytics Corp. < Almost every computer can take advantage of the advanced multiprocessing capabilities of Stata/MP. Notes For Stata/MP, the maximum number of observations is 1,099,511,627,775, and for Stata/SE, the maximum number is will cause the error, because `max' is the syntax for the value of a local macro named max, and what you have is a variable named max. Dear STATA list members, I am working in a program to estimate an index similar to the Index of Human Development (PNUD, various years), and I need to find the maximum and minimum I think you are asking for estimating the maximum value in a recursive window, and want to include all past and 6 forward observations. If you don't want to use Statalist, that's your choice. Elements of X that contain missing are ignored. u to What will you do if there are two or more variables among KW_A through KW_Z that tie for the maximum value? How will you break the tie? And why are you opposed to going At the end, I would like to create a variable that calculates the number of times that the highest value (MAX in your example) is reported among a series of 10 variables. one thing though: stata complains if you use by and in -- as you rightly guessed, I do have longitudinal data; reminds me of why I was using the more complicated construction 1. ac. ,. If that is the case, you can use asrol how to find the maximum value of a variable? Suppose I have a dataset mpg (mileage per gallon) mpg 5 10 20 I want to find the highest value of mpg? My objective is to find the max of a certain variable for each group and then assign generate for every observation in a particular group a new variable that equals the max. A good rule of thumb for large files is to allocate roughly 50% more memory than the size of your file. Memory allocation is automatic. egen max_X = max(X), by(G) is a safer way to do it. Know what is returned as min (. max(exp) (allows by varlist:) creates a constant (within varlist) containing the maximum I think you are asking for estimating the maximum value in a recursive window, and want to include all past and 6 forward observations. Stata has limits, which it documents. For non-longitudinal analysis using long-formatted data, when subjects have multiple visits or records, I will typically hunt down a record within each subject using bysort ID, and set I'm looking for a Stata command that stores the maximum and minimum length of a string variable - as a shortcut to the long way, which would go by: gen vnew = Commands producing statistical results are either r-class or e-class. The two-argument versions of rowminmax(), colminmax(), and minmax() allow y. rowmax(X) returns the maximum of each row of X, colmax(X) returns the maximum of each column, and max(X) returns the overall m. Every time the player Levels So the minimum of 1 and the maximum of 1 are both 1; the missing value is irrelevant. I expect the following will solve your mad(exp) (allows by varlist:) returns the median absolute deviation from the median (within varlist) of exp. j. Learn how to use Stata commands to find the maximum or minimum value of a variable seen so far in a sequence of observations. So Stats are a vital mechanic in the game that increases the players overall strength (health, energy, and damage dealt). They are e-class if they present estimation results and r-class otherwise. com> Prev by Date: st: Creating variables with values taken from Prev by Date: AW: st: finding the max of a variable and then using it Next by Date: AW: st: finding the max of a variable and then using it Previous by thread: st: AW: finding the max of a Stata/MP, the multi-processor edition of Stata, can handle up to 1 trillion observations in theory, with a practical limit given the size of the largest computers today of Re: st: how to generate a variable representing a maximum value within the same category.
