Using the value labels (assuming that they exist) to produce a string variable is the safest approach, but consistency of spelling is vital. Stata has a wide array of tools to work with dates. This module illustrates the power and simplicity of Stata in its ability to reshape data files. 70141173319×1038 1. // third try--a little long but works and is clear gen weightCost 2reshape—Convertdatafromwidetolongformandviceversa Syntax Overview long wide i j stub i stub1 stub2 1 1 4. Commented Jan 3, 2018 at 14:53. Let’s use an example. 1. I can see the full-length number in the data view window but when I tabulate this variable, in the results window it shows the shorthand version (e. Similarly, byte, int, and long are usually used to hold integers. Floating-point types 2. byte, int, and long are said to be of integer type in that they can hold only integers. On windows it is always 32-bit. You are not doing it here, but using round() at all with second arguments < 1 is something I continue to advise against unless the second argument is a power of 2. 00011001100110011001101 (base 2) or more correctly, to. Let's begin by opening an example dataset from the Stata website and listing the first five observations for the variable chol. unsigned long myLong = 5; float myFloat = (float)myLong; (float)myFloat is the key. In our data, the category Binance is coded as 1, and the category XYZ is coded as 2. They still show a mean of >1 when summarized, though. Long is a type We will need to convert these variables to numeric data before we can use them with Stata's statistical features. Convert long to float in C. one of my variables is age which is a numeric var stored as float. Training. 0, 244 characters and in Intercooled Stata 7. comCopyright 2011-201 Converting a string date. 5. I need it to be numeric in order to treat the and float() then rounds that long binary number to. . 795×10−8. Qty: 1 $11,763. The context is that I earlier wrote destring (with help from William (Bill) Gould) and have often needed it myself ever since and it seems to be used quite often. , from Below we can convert it to numeric by include the ignore(X) option that tells destring to convert the variable to numeric and when it encounters X to convert that to a missing value. A string variable will be promoted whenever it gets too long as the result of a replace,subject to the upper limit associated with your executable (in Stata/SE 7. With respect to identifiers, they should remain string; there's no expectation of doing math with their value. If you wish to do convert numeric data into string or vice versa, Stata provides commands like ‘encode’, ‘decode’, ‘destring’ and Numeric variables can be stored as byte, int, long, float, or double. while I read somewhere that the automatic STATA maximum From "Alok Bohara, PhD" < [email protected] > To [email protected] Subject st: Converting UTM (northing/easting) to long/lat using Stata: Date Wed, 04 Jul 2012 18:08:47 -0600 This video demonstrates how to convert a string variable to a numeric variable in Stata using the *destring* command. Wholesale Price Index t int %tq quarterly date ln_wpi float %9. new numeric variables are generated as float without an explicit variable type, you can set type otherwise. 0g //This makes it so V1 looks like a full number in the data visualizer without scientific notation gen V2 = "0000000000000" //Just a 13 digit long arbitrary string format V2 stata. Mitchell. , swimming upriver) as the original author of tostring, but it's long since an official command and if this is a bug or misfeature it's StataCorp's, not mine. float, int) goes in the parentheses and directly after This means that their means are 0 when collapsed. That is the way most numerical analysts would convert digit accuracy between bases, so we could claim 7. You cannot get means, you cannot do a regression, you cannot do an ANOVA, etc encode—Encodestringintonumericandviceversa Description Quickstart Menu Syntax Optionsforencode Optionsfordecode Remarksandexamples References Alsosee Description Sometimes, data that look like numbers are actually stored as strings. 0g. 6597311 3. clear input float id strL visit_history 1 "2021-06-03,2020-12-07" 2 "2021-07-30,2020-12-28,2021-02-02" 3 "2020-09-12" 4 "2021-03-10,2021-02-02" end 如何将stata中的long变为float的存储格式用real函数，可以将这个问题解决了，gen 新变量=real（原字符变量）来实现，该命令会把有非数字的变量变为缺失值。 A dataset with 11 variables was imported to STATA using File -> Import Excel spreadsheet. But whenever I copy paste numerical data into the program, it makes the variable (column) strings instead of e. text datetime— Date and time values and variables 3 In the remaining text, we will use the following notation: tc: a Stata double variable containing SIF datetime/c values tC: a Stata double variable containing SIF datetime/C values td: a Stata variable containing SIF date values tw: a Stata variable containing SIF weekly date values tm: a Stata variable containing SIF monthly date The fipscode needs to be 11 digits long: 2-state, 3-county, 6-tract with leading (and trailing) zeros when necessary. These show common examples of reshaping data, but do not exhaustively demonstrate the different kinds of data reshaping that you could encounter. you hav So I am trying to make an Excel sheet into a STATA data file. 0g ----- Sorted by: t The display format for the variable t is %tq which indicates a quarterly date. recast—Changestoragetypeofvariable Description Quickstart Syntax Option Remarksandexamples Alsosee Description recastchangesthestoragetypeofvariables.
