All language subtitles for 3. SETSEED

Next we discuss an important concept of setting seed
1

So when we are running random functions it will be always giving us random values
2

That random value is being generated through a function
3

If you give it an input through a seed it will give a particular value to you
4

So seed
5

Comes to use many times
6

For example if you have set of random values and you want to get the same set of random values again you'll set a
7

seed before getting random values
8

If I am teaching and I am showing you an example
9

And my example has some random values and If I want you to have the same random values
10

I will set the sead
11

And I'll let you know what is the value of that seed so that you can set the same seed
12

We both will get the same random values
13

This is what we will do in the example also we will set seed
14

And both of us will get the same values
15

Seed value can be between -1 to 1
16

And both of them can be included
17

and it can have any decimal value also
18

So, this is how we set a seed
19

We will write select set seed of
20

Point 5
21

Once you have set the seed
22

When you run the random function it will give you a particular value
23

Every time you run
24

The random function after setting seed at .5 it will give you the same random value
25

The second time you run the random function, it will give you new value
26

But this value will
27

Always remain same what this means is, whenever you set the seed to 0.5 the first random
28

Function will give you same value, the second random function will give you a different value
29

than the 1st random function but it will be always same
30

If you do not understand this, let us look at an example you will get what I am trying to say
31

So let us first select setseed to 0.5
32

Setseed has Run successfully
33

Now let us
34

run the random function. select random
35

So this gives a random value of .5500
36

25. Let us write this is as a comment so that we remember it
37

Now run the random function again
38

So it is now given a value of
39

0.29531
40

Now let us set
41

Seed again
42

Write select set seed 0.5
43

Now the seed is again back to .5
44

Now when we run the random function
45

we'll get
46

The same value
47

I hope if you are doing it with me you are getting the same values as I am
48

let us run the random function again
49

This will be same as
50

.295311
51

So this is what setting seed helps you do. It helps to get
52

the same set of random values
53

So that you can repeat the calculations
