How do you find the mean of a column in Stata?
How do you find the mean of a column in Stata?
mean produces estimates of means, along with standard errors. stdize(varname) specifies that the point estimates be adjusted by direct standardization across the strata identified by varname. This option requires the stdweight() option.
What does Rowmax mean in Stata?
rowmax(varlist) may not be combined with by. It gives the maximum value (ignoring missing values) in varlist for each observation (row). It gives the (row) median of the variables in varlist, ignoring missing values. If all values in varlist are missing for an observation, newvar is set to missing for that observation.
What does _n mean in Stata?
observation number
Introduction. Stata has two built-in variables called _n and _N. _n is Stata notation for the current observation number. _N is Stata notation for the total number of observations.
What does a period mean in Stata?
This is done by what Stata calls value labels. Finally, under the rep78 variable, which looks to be numeric, there are some cells containing just a period (.). The periods correspond to missing values. Looking at the data in this fashion, though comfortable, lends little information about the dataset.
What is the mean command in Stata?
Stata provides the summarize command which allows you to see the mean and the standard deviation, but it does not provide the five number summary (min, q25, median, q75, max). If you want to get the mean, standard deviation, and five number summary on one line, then you want to get the univar command.
What is Rowtotal Stata?
rowtotal(varlist) [ , missing ] may not be combined with by. It creates the (row) sum of the variables in varlist, treating missing values as 0. If missing is specified and all values in varlist are missing for an observation, newvar is set to missing.
What is _N and _n in Stata?
Stata has two built-in variables called _n and _N. _n is Stata notation for the current observation number. _N is Stata notation for the total number of observations.
