Basically what i am using is (tab var1, miss) to figure out missing values in a single variable, but i wonder if i have to repeat the same command 100 times for each variable in my data-set and then to look for top 5 variables with the

The “missing-data correlation matrix,” i.e. pairwise deletion of missing data. Such a matrix is computed by using for each pair of variables (Xi, Xj) as many cases as have values... In Stata, you can use either the .correlate or .pwcorr command to compute correlation coefficients. The following examples produce identical correlation coefficient matrices for the variables …

Learning a little bit more about Stata’s built-in functions can be very convenient (sometimes necessary)—shorter codes, faster processing, more facebook time. Using inlist(), the equivalent code is: how to get the average volume Clarification: if I have a variable with three unique values, a, b and c, I want to store those in a macro variable so I can later take another dataset and select observations that match one of those values.

## How To Find Values Of Variables In Stata

The command unique without a by reports the number of unique values for the varlist. With a by it does the same, but also creates a new variable (_Unique by default but can be named in the gen option).

- 5/02/2013 · In the code above, Stata creates nine new variables (x1991 to x1999) using the -gen x`y'-command. Here `y' is used to refer to the local macro defined in the loop control. As the -gen- command creates each of the new variables, they are set equal to the value of x1990, plus some number of years (`y’ – 1990), times the average annual change in the x variable ((x2000 – x1990)/10).
- The problem is an analogue of this one: I have values 0,0,0,0,0,1,1,1,1,2,2,3 and want to see 4 quartile-based bins with equal numbers of values in each. Even with sample size of multiple of 4, that can't be done because of ties.
