Can I get the quantitative techniques books freely from the internet??? Give me inages of some good books

As you want free pdf book for Quantitative Techniques, so I am providing following books:

Free Quantitative Techniques Book
Chapter 1 – Introduction

Let’s start with a cautionary tale

Consider the following: A study of the incidence of kidney cancer in the 3,141 counties of the United States reveals a remarkable pattern. The counties in which the incidence of kidney cancer is lowest are mostly rural, sparsely populated, and located in traditionally Republican states in the Midwest, the South, and the West.
What do you make of this?
Gates Foundation made substantial investment in small schools based on a study that showed that the most successful schools, on average, are small.

It turns out we are not very good statisticians. We like stories, but not really the source of the story. This causes us to make mistakes in evaluating the randomness of truly random events. For example take the sex of 6 babies born in sequence in a hospital. Consider three possibilities:
BBBGGG
GGGGGG
BGBBGB

Are the sequences equally likely?

There is a widespread misunderstanding of randomness.
Streaks in sports

We pay more attention to the content of messages than to information about their reliability, and as a result end up with a view of the world around us that is simpler and more coherent than the data justify
Many facts of the world are due to chance. Causal explanations of chance events are inevitably wrong.
Even faced with data to the contrary, we tend to stick to our stories

We see this illusion of understanding used in a lot of business books. “Let’s look at what previously successful people did and copy them”. Stories of success and failure consistently exaggerate the impact of leadership style and management practices on firm outcomes.
A study of Fortune’s “Most Admired Companies” finds that over at twenty-year period, the firms with the worst ratings went on to earn much higher stock returns than the most admired firms.

Regression to the mean
This course deals with statistics. Two types:
Descriptive Statistics
Inferential Statistics – makes possible the estimation of a characteristic of a population based only on sample results.

The first part of this course will deal with descriptive statistics but we will quickly move to inferential stats – more interesting and useful for what we are after.

The second class (HCAI 5221) deals with the application of statistics to decision making in the business setting.

Types of data
Categorical random variables – yield categorical responses – yes/no, agree/disagree, etc.

Numerical RV can be discrete or continuous

Data Collection
Typically data are collected through sampling. The most common sample is a Simple Random Sample – every individual in the population has the same probability of being chosen. This can be done with replacement or without replacement.
Stratified Sample – The N individuals are first subdivided into separate subpopulations, or strata, according to some common characteristic. – this allows for oversampling of some groups to ensure representation.
Cluster Sample – The N individuals are divided into several clusters so that each cluster is representative of the entire population. Then a random sample of clusters are taken and all individuals in the selected clusters are studied. Counties, election districts, families, etc.

Problems with Sampling

Selection Bias – occurs when certain groups in the population were not properly included. – black/white wage differential, medical trials.
