In Stata, the seed is a positive integer (between 0 and231−1) that Stata maps onto the state of the RNG. The state of an RNG corresponds to a spot in the sequence. The mapping is not one to one because there are more states than seeds. If you want to pick up where you left...
EXAMPLE 1: Create a new variable and assign a constant In this first example, we’re going to add a new variable to the datafame and assign a constant value for every row. Let’s think about something specific. Say that you’re working with this dataset, and all of these people work...
How to change the units of a drawing in AutoCAD products, such as from Imperial (feet/inches) to Metric (mm, cm, m), or vice versa. These are the main methods to convert drawing units. Alternative 1 (preferred method): Use -DWGUNITS Enter the -DWGUNITS c
