Invalid psu variable name stata

psu is n or the name of a variable (numeric or string) that contains identifiers for the primary sampling units (clusters). Use n to indicate that individuals (instead of clusters) were randomly sampled if the design does not involve clustered sampling. In the single-stage syntax, psu is optional and defaults to n. st: invalid name problem when coding my own ml problem Apologies to all if this is a question that did not warrant the use of statalist, I've looked for a couple days for the answer to my problem and haven't been able to find it. Stata uses the in or of to determine whether the next word is the first element of the list or a type of list. Researchers occasionally receive data sets created in other programs where the variable names are in upper case letters. Since Stata actually cares about case, upper case variable names can be .

Invalid psu variable name stata

Hello, I am fairly new to stata and am just beginning to analyse some secondary data. I am setting up the sampling design using: svyset. Here is a tiny example showing how to use the survey commands in Stata. The output is below, and it tells you the pweight, strata, and psu variables so you. svyset psu [ weight ] [, design options ] [ || ssu, design options ] [ options ] psu is n or the name of a variable (numeric or string) that contains identifiers for the primary .. otherwise, the estimate of the population size will be incorrect. Finally . 1, page 9, quoted below, "cluster" is the name of the *second* stage . know the PSU variable >> to use probability weights is also incorrect. RE: st: Definition of strata and PSUs when svysetting but when I svydes variable, single stage(2) no single PSUs are displayed. . Stas Kolenikov, also found at keepitlocked.net > > Small print: Please do not reply. Let's make up some variable names to represent survey design characteristics: Prior to Stata 9, where svyset accepted only the first-stage design variables, one aware that specifying an FPC implies there was no sampling within the PSUs. Subsetting the data may cause an incorrect number of PSU's to be used in the Stata subsets to only those observations where ALL the following variables are. I am not sure what variable to specify in the PSU and strata. For that survey, v is incorrect and should be reconstructed with "v = int(v/)". If you make changes using original variable names, as just suggested, you Following is a response from Senior DHS Stata Specialist, Tom Pullum.

When there is only one PSU within a stratum, there is insufficient information with which to compute an estimate of that stratum's variance. Therefore, it is impossible to compute the variance of an estimated parameter when the data are from a stratified clustered design. Stata uses the in or of to determine whether the next word is the first element of the list or a type of list.

Jun 19,  · st: Variable name length limit. The limit on length of variable names is in recent versions of Stata 32 characters and not adjustable. 3. The issue behind most limits is memory, but my strong impression is that the issue with variable names is just space to show results. Imagine even a modest increase in variable name length to 64 characters. Sep 13,  · A Stata variable name can contain up to 32 characters in any version of Stata (Small, Stata/IC, Stata/SE, or Stata/MP). Not all characters in the keyboard, however, are allowed in naming variables. A variable name may contain only the digits 0 to 9 and upper or lower case English alphabets (A to Z); and the first character cannot be a number. The variable name is Q3_10 and the label is Q st: invalid name problem when coding my own ml problem Apologies to all if this is a question that did not warrant the use of statalist, I've looked for a couple days for the answer to my problem and haven't been able to find it. Of course, what is really going on here is that we are trying to use an invalid variable name. Recall that variable names must begin with a letter or an underscore. Trying to specify a variable name *type thus causes SAS to hiccup. SAS does not recognize *type as a valid variable name.
