Statistics: Multivariate Analysis Research Data Collection Thesis

… Statistics-Multivariate Analysis

Research data collected using the quantitative approach can be analyzed and interpreted in different ways, using either the univariate, bivariate, or multivariate analysis.

Bivariate analysis looks at the relationship between two variables. It is commonly analyzed and interpreted with the aid of the cross-tabulation or cross-tab, allowing the researcher to check the interaction between the two variables under study. The variables under study are called the independent (or predictor) variable and the dependent (or outcome) variable. The interaction between the two is reflected in the cross-tab, and each interaction can be expressed in either frequencies (raw count) or percentages, or both. It is critical in bivariate analysis to establish whether the relationship observed is significant or not. Determining the significance of the relationship…. [read more]

Benefit Analysis Article Critique

… Decline in tobacco linked morbidities would bring reduction in the health care expenditure, which was previously done for the betterment of the public at large. Reduction would be apparent in the hospital costs, in pharmaceuticals, in other medical services, in health consultations and in nursing homes. Third parties would be benefitted by the reduction in smoking, like for example many industries would earn more revenue when smokers will switch to non-tobacco products, while others would benefit by the productivity of the workforce. Tobacco industry losses are balanced by the net income generated from other products. With the reduction in smoking, the surrounding air would be clean; few people would become passive smokers, moreover, the parental heed required for low weight babies would be reduced (Report,….

Regression Analysis the Methodology for Analyzing Data Research Paper

… Regression Analysis

The methodology for analyzing data is just as important as having a strong foundation for collecting. Within qualitative and quantitative research applications, the use of statistics is a common practice. One of the most used statistical analysis techniques is what is known as regression analysis. This current report explores the processes within regression analysis in what environments the methodology is appropriate for use in to analyze data.

Regression analysis uses statistical formulas in order to show a correlation between particular variables. Sykes (2012) posits that it is "a statistical tool for the investigation of relationship between variables." It is essentially a way to quantify the relationship between the variables and manipulate environmental changes to forecast what impact they would have on such variables…. [read more]


Regression Analysis Is the Technique Term Paper

… Regression analysis is the technique used to express the linear relationship between two variables. With this technique we can estimate the value of the dependent variable (Y) based on a selected value of the independent variable (X). This kind of analysis is mostly used to determine if sales numbers of a product a are related to the number of TV advertisements for that particular product during a specific timeframe. The mathematical equation for the line used to estimate the value of variable Y on the basis of variable X is also known as the regression equation (general form of linear regression equation: Y1 = a + bX) (Lind, Marchal, & Wathen, 2005).

Y1

= read Y prime, is the predicted value of Y for a…. [read more]


Regression Analysis and Business Rules Essay

… Linear regression can also be utilized in the creation of trend lines, which uses past data to predict future performance or trends. Generally, trend lines are used in business to show the progress of financial or product attributes over time. "Stock prices, oil prices, or product specifications can all be analyzed using trend lines" (Keener, 2011).

In business the capital asset pricing model was developed using linear regression analysis, and is a frequent measure of the instability of a stock or investment. The process for determining this is done by linear regression. Linear regression is key in evaluating the risk that is linked with most investment vehicles (Keener, 2011). This is very important in the business world as money and investments are crucial to most…. [read more]


Regression Analysis on Retirement Definition Term Paper

… Lets assume that different individuals have characteristics (either observed or unobserved) that make them either more or less tend to retire at an early age. Let [X.sub.i] be one characteristic, such that high values of [X.sub.i] are linked with earlier retirement: [differential]R/[differential][X.sub.i] < 0.

It can also be asked as what the effect of [X.sub.i] is on asset holdings at some time earlier to retirement. Since [X.sub.i] function not directly through the retirement age in the above model and not directly on either assets or consumption, then:

[differential]A (t)/[differential][X.sub.i] = [differential]A (t)/[differential]R [differential]R/[differential][X.sub.i] > 0.

A characteristic that makes a person more inclined to retire early also persuade that particular person to hold more possessions than otherwise.

This can be understood by a simple interpretation,…. [read more]


Multivariate Analysis of Parametric Data Essay

… Maddox's research design involved a qualitative analysis of consumer behavior in regard to their usage of Web sites for the purpose of gathering prescription drug information as well as product requests. The research design involved the use of a questionnaire to measure the research questions. The questionnaire was placed online on a website belonging to one of the major pharmaceutical firms for a 2-week period., the responses were rated on a five-point (Likert) scale that ranged from 1 for very unimportant or unlikely to 5 for very important or likely.

Economic and Quantitative Analysis Topics Term Paper

… The United States has shifted in a major way on two different occasions over its existence. First, they went from an agrarian economy to an industrial one and now they are shifting to a service/knowledge foundation while the once dominant manufacturing industry in that country is becoming an afterthought except when speaking of advance/high-tech manufacturing. If someone were to analyze the United States economy over its entire existence, using a singular and fixed model would be asinine and obtuse because of these seismic changes that have occurred. Looking at the United States economy now through a year 1840 lens would be silly.

In a similar vein, looking at Nigeria now would require a certain model and that model would exhibit certain patterns and trends. However,…. [read more]


Linear Regression Models (Meier, Chapter 18 Article Review

… Linear Regression models (Meier, Chapter 18 / 19)

These are used in order to determine whether a correlation (or relationship) exists between one element and another and, if so, in which direction (negative or positive).

The two variables are plotted on a graph. Independent variable on the x line (horizon); y- variable (dependent) on the vertical line. The pattern between them is called the 'slope'. The point where X and Y intersect online is called 'intercept'.

The theorem used tells us that the slope of the line will be equal to the change in x (IV) given changes of y (DV). The shape of the slope (their direction and gradient) describes the relationship between X and Y.

Linear regression, as are the previous models, is…. [read more]

USE of STATISTICS in RESEARCH and ANALYSIS

This paper concerns itself with the use of statistics as a means and the important tool in research and analysis -- both in the scientific and social sphere. Statistics can be defined as a study of variability and enumeration. It tries to quantify and enumerate uncertain things in a scientific manner. That is because there is an element of uncertainty in all affairs of research and information processing. For example measurements made by scientists and other people are mostly uncertain in some way. One example cited by Kault…. [read more]

Statistical Analysis of Suicide and African-American Culture

From a general statistical standpoint, the risk of suicide is lower among black Americans than their white counterparts. However, racial distinctions can provide a useful framework for connecting certain cultural and environmental realities to suicidal tendencies. This is the imperative that underscores the review below of four corresponding articles:

The first article considered here is that provided by Neeleman et al. (1998), entitled "Suicide acceptability in African- and white Americans: the role of religion" and originally published in Vol. 186, No. 1 of the Journal of Nervous Mental Disorders.

… And the R-Square value is 0.884, and the MSE is 2,850,735.33.

Residuals are shown in the ANOVA as 8,678,396, 57.

Conducting a Stepwise Forward Regression yielded similar results.

C. Findings

Given that the formula for the R2-value is:

R2 = SSR/SSTO = 1?SSE/SSTO

It can be seen that the R2-value increases as more variables are added. This means that the "best" model cannot be the model with the largest R2-value. Instead, the R2-values can be used to find the point where adding more predictors doesn't make sense since they don't fit the criteria. In other words, the additional predictors only yield tiny increases in the R2-value. Essentially, then, both the magnitude (number of predictors) and size of the increase in R2 are considered.
