How to decentralize variables in Stata

1. According to Hou Jietai: the so-called centralization refers to subtracting the mean value of a variable from its expected value. For sample data, each observation value of a variable is subtracted from the sample average value of the variable, and the transformed variable is centralized
for your question, subtract the mean from each measurement.
for your question, subtract the mean from each measurement.
2. Only iron pick can dig ore and water in the mine cave. It's better to bring some wood and a fire into the mine cave. You can only knock round stones by the river to have a small chance to proce iron ore. The Iron pick is not useful for iron ore. It's the same to decide what equipment you wear. The iron spear and crossbow must be available, and then according to the cold and hot conditions of the mine cave you want to go to at that time
3. In Stata, the matrix and variable can be freely transformed. The commands are mkmat and SVMAT respectively. Regression is easier. Just use Reg to do it
4. Standard treatment is required to be used for standardizaization processing of variations (x-value value)/divided divided divided criteria differences (x-value value)/cbr/br//>method1 - gengengengen

The steps of renaming Stata variables are as follows:
1. Open the data file and enter list name to view the default Stata variable name
7. I am also interested in this matter, in the National People's Congress forum to search a complex ADO, the method is really not simple
1. Open DTA data set
2. Run the ADO file of svvarlbl (download address:)
the code into the do file editor of Stata and save it as D: &# 92; data\ Outlabel.do, and then enter: do D: &# 92 in Stata; data\ Outlabel. Do
the first two steps can also search svvarlbl, all directly, and then install
3. Input: svvarlbl using varlabel. Log
the output variable label is in log text format. If you want to turn it into excel again, you can use Stata or sas to read it into the program, convert it into excel, or and paste it directly
think of a way to save the country by curve. First, use stat / transfer to convert Stata data file into SAS, then find a software EpiData, import the SAS data file in EpiData, and open the exported *. Chk with Notepad, all of which are clear.
