Factor Analysis
The very early stages of most advanced statistical investigations can be characterized
as fishing expeditions.

Lecture: Elements
Associated with each derived factor is a quantity known as an eigenvalue, which
corresponds to the equivalent number of variables which the factor represents.
The important of an eigenvalue rests on the decision we must make as to how ma

Multivariate Regression Equation:
Y = a + b1X1 + b2X2 + b3X3 biXi + e
Multiple Regression
Multiple regression is an extension of simple regression but differs from it in that it aims
for full model specification. This means th

Lecture:The Operationalization of the Theory
Operationalization is the process of conversion or redefinition of our relatively abstract
theoretical notions into concrete terms that will allow us actually to measure what we are
after.

Lecture: The Analysis of Data and Bivariate Analysis
Bivariate Analysis examines two variables simultaneously to look for a relationship
between them, searching for evidence that variation in one variable coincides with
variation in the other.

Richard Feynman:
If the theory disagrees with the empirical evidence, it is wrong. In that simple
statement is the key to science. It does not make any difference how beautiful
your guess is. It does not make a
