Simple linear model
Ordinary Least Squares
Application of statistical techniques to problems in finance
Estimating and testing relationships between variables as
understanding what quantitative methods in finance are, and what they are best used for, rather than trying to achieve this mastery on their own. But for quantitative methods to be used and appreciated in the investment community, one needs a primer on the topic for a nontechnical audience. The current monograph...

two together, we get effective solutions for the practical problems. The basic
approach in GP modeling is to attempt to express a practical problem, such as an engineering analysis or design problem, in GP format. In the best case, this formulation
is exact; when this is not possible, we settle for an...
Although the relationship between the response variable Y and the explanatory variable X is a straight line in a simple linearregression, all data points in this regression are not laying on this straight line.
The differences are the residuals which display how much the observed values differ from the...
Objectives of Analysis
We will attempt to model the “Future Total Reserves” of a country using continuous current global economic monitors. We aim to obtain a good model that will be reliable in predicting the future reserves using current data.
In this question we aim to obtain a regression relationship using...
problems. ANNs, like people, learn by example. An ANN is configured for a specific application, such as pattern recognition or data classification, through a learning process. Learning in biological systems involves adjustments to the synaptic connections that exist between the neurones. This is true of...
Sections 1.1 and 1.2
I. Observation vs. Experiment
A. Observational study: Record data on individuals without attempting to influence the responses. We typically cannot prove anything this way.
B. Experimental study: Deliberately impose a treatment on individuals and record their responses. Influential...
cost-behavior estimation 2. Describe linear cost functions and three common ways in which they behave 3. Understand various methods of cost estimation 4. Outline six steps in estimating a cost function using quantitative analysis 5. Describe three criteria used to evaluate and choose cost drivers 6. Explain and...

of individuals. For now, we are concerned only with the fact of such hierarchies not their provenance. The principal applications we shall deal with are those from the social sciences, but the techniques are of course applicable more generally. In subsequent chapters, as we develop the theory and techniques...
sensor or instrument;
4. • a careful study of one or more of the properties of a sensor or instrument;
5. • a comparison of methods of measuring the same thing.
We will provide you with a list of possible activities from which you can choose.
You are assessed on your ability to do the following:
variable = true and meaningful zero point
- Discrete variable can only take certain values (whole numbers) on the scale, continuous variable can take all the values on the scale.
* Validity and reliability
Measurement error = a discrepancy between the numbers we use to represent the thing we’re measuring...
CAPM - Risk and Return
Risk and return are central concepts in finance. How to deal with risk is a key issue in
financial industry. In this chapter, we study risk and return systematically.
Some motivation examples:
Example 1: the relationship between risk and return
Small stocks had...

I will choose the temperature to be the explanatory variable and the growth to be the response variable because I want to investigate if there is a relationship...
