The second block of code, using Stata matrices, is limited by matsize. The Mata code is not, and uses less memory than the Stata matrix solution in any case by the use of views. All of the check variables being identically zero shows that the two methods are identical. Kit Baum, Bosto...
VarA5 VarA6 and the data from VarA to be transferred/copied to the newly created variables (sysmis, if the variable has no code for the new variable; VarA2 VarA3 and VarA6 will have missing values for first row of VarA). Wondering, if any stata command/program can be used to do it...
Assumption #3: You should have independence of observations (i.e., independence of residuals), which you can check in Stata using the Durbin-Watson statistic. Assumption #4: There needs to be a linear relationship between (a) the dependent variable and each of your independent variables, and...
#To print the range of salary packages<br> range.sal <- range(read.data$empsalary)<br> print(range.sal) Output: [1] 20000 36000 #To print the details of a person with the highest salary, we use the subset() function to extract variables and observations<br> max.sal <- subset(read...
To delete a single variable, you can use the delete keyword followed by the name of the variable. To delete an array of variables, you can use the delete[] keyword followed by the name of the array. Can you undo commands in Stata?
First, we will just perform the normalization directly in the middle of our analysis script. In Stata, we call analysis scripts do-files because they do something. Let’s normalize the variable namedx. I don’t like to change the content of existing variables, so I am going to create a...
Hi, I am trying to read a 3 GB stata file to analyze on python. I just completed the dask tutorials on datacamp. This code works: data = pd.read_stata('/Users/sherrymukim/Documents/nfhs/IAHR71DT/IAHR71FL.DTA',chunksize=100000) But the fo...
the Wald test is commonly used to perform multiple degree of freedom tests on sets of dummy variables used to model categorical variables in regression (for more information see our webbook on Regression with Stata, specificallyChapter 3 - Regression with Categorical Predictors). Another example is ...
Stata is the favorite tool of all the data scientists out there as it accommodates data manipulation, visualization, and manipulation without the need to go for different software or tools for each task. Stata is mainly used by researchers and academicians in the fields of political science, ...
This table is halfway to what we want to see. Each statistic has its own column, but there are many empty cells because each statistic gets a unique column. Please note that if you have the same type of summary statistics for all the variables in the table, you may stop at this step...
