Is there a way to achieve this Thanks in advance, best, Harvey. Like any function in Stata it cant be issued on its own but only within other commands, usually generate or replace or display. clear cd 'C:UsersjannicDesktopsandbox' webuse grunfeld, clear keep if company <8 the command below does not work unfortnately: local max maximum (invest) now local 1486.7 should be the result. The maximum length of the contents of a macro is fixed in Stata/BE and settable in Stata/SE and Stata/MP. The Stata function max() requires two or more arguments and returns the maximum of those arguments. In practice, both editions are limited by memory. I am using Stata IC 12 (up to date) and working on DHS data, I had no problem with working on most of the DHS files for the past years, but currently I can't open the Individual Recode file on Stata because the number of variables in the file( 16,000 variables) exceeds the maximum number of variables allowed by Stata IC. It's just the same as the standard -generate-, except whatever follows the equals sign (including any if-s or in-s) becomes the variable label. For Stata/MP, the maximum number of observations is 1,099,511,627,775, and for Stata/SE, the maximum number is 2,147,483,619.
or quantitative variables can be useful in a number of circumstances. blank data set (data frame) with R 2 A maximum of 2,047 variables can be saved to Stata 5-6 and Intercooled Stata 7-13 This.
NB: Some of these methods assume that the values don't have spaces or symbols that Stata wouldn't accept in the variable names - otherwise, assign only the variable labels and then see below how to convert labels into names. This set of notes describes how to use the computer program Stata to recode.
How to rename variables according to their labelsīonus: How to assign variable names as their labels The predictor variables of interest include student gender and whether or not the student took. The outcome variable is binary (0/1): admit or not admit. Conclusions: Our results suggest that ambient levels of PM2.5 and ozone can reduce the high-frequency component of heart rate variability in elderly subjects living in Mexico City and that subjects with underlying hypertension are particularly susceptible to this effect.From the first AND second rows of observations Suppose that we are interested in the factors that influence whether or not a high school senior is admitted into a very competitive engineering school. Participants with hypertension had considerably larger reductions in their HF-HRV (high frequency-heart rate variability) component in relation to both ozone and PM2.5 exposure. reveal that there are 74 observations on 12 variables in this data set. After adjusting for age and heart rate, we observed a strong decrease in the high frequency component of heart rate variability and the average 24-hour concentrations of PM2.5. 46.2 A SAMPLE SESSION Stata comes with example data sets that are used in on. Daily 1-hour maximum ozone levels ranged from 47 to 228 ppb. The 24-hour average levels of indoor PM2.5 ranged from 15 to $67\ \mu $.
Results: Of the initial 42 screened participants, 34 (81%) were followed during the study period. Stata/BE allows datasets with as many as 2,048 variables and 2 billion observations. Stata/SE can analyze up to 2 billion observations. Stata/SE (up to 10,998) and Stata/MP (up to 65,532) can fit models with more independent variables than Stata/BE (up to 798). Levels of ozone and other atmospheric pollutants were obtained from a nearby automated monitoring station. Stata/SE and Stata/BE differ only in the dataset size that each can analyze. Indoor and outdoor PM2.5 (particulate matter less than 2.5 mm in diameter) were measured daily at the nursing home. Background: Suspended particles and ozone have been associated with varying degrees of cardiac autonomic dysfunction Methods: In Mexico City, residents from a nursing home underwent heart rate variability analysis every other day for 3 months.
