Building a SAS Data Set - 1
List Input reading raw data separated by space
Example 1.1 (deal with missing values)
data listinp; input id height weight gender $ age; datalines; 1 68 144 M 23 2 78 202 M 34 3 62 99 F 37 4 61 101 F 45 ; proc print data=listin
Building a SAS Data Set - 3
LAG function assign the value of a variable in the last observation
Example 3.1
data external; infile `a:\dataset2 \china#1.dat'; input year total exports imports; lag_exp = lag(exports); ch_exp = exports - lag_exp; lag_imp = l
SAS - An Introduction
What is SAS Software
SAS software started in the 1970s as a software package for statistical analysis. Today the SAS software includes graphics, spreadsheets, online data entry, compilers for C programming language, tools for buildin
Inferential Statistics

Today, we will make the first step towards Inferential

The Continuous Random Variable
A continuous random variable Y has the following properties:
1.
2.
3.
Y takes on an uncountable infinite number of values
The cumulative distribution function F(y) is continuous
The probability that Y equals any one particu
Definitions
A random variable Y is a numerical-valued function
defined over a sample space.
Each simple event in the sample space is assigned a value
of Y.
Example: assigning a numerical value with the outcome of
a coin toss.
