It also has an extensive set of functions to compute probability distributions (needed for p-values) and their inverses (needed for critical values), including normal() for the normal cdf and invnormal() for its inverse, see help density functions for more information.

Let’s begin by simulating a bivariate VAR(2) process using the following specification, \[\begin{bmatrix} y_{1,t}\\ y_{2,t} While it is true that the basic arithmetic operations will not help, there exists a function in Stata that will return the same first 2-digit code. This is the int() function. int(x) returns the integer obtained from dropping the digits after the decimal point of number x. For example: gen string4=int(code/10000) Fortunately, Stata has functionality built in that allows you to identify all the files in a folder. Not just that, but it also places the name of each file in a local list which allows you to easily append them and even show their source file in the final dataset.

' as well. If we wanted to include just the valid (non-missing) observations that are greater than or equal to 4, we can do the following to tell Stata we want only observations where rep78 >= 4 and rep78 is not missing .

For simplicity we will adopt the terminology of survival analysis, referring to the event of interest as ‘death’ and to the waiting time as ‘survival’ time, but the techniques to be studied have much wider applicability.
