HOME ASSIGNMENT Analysis of Auto Parts Industry/ USA /deviations‚ betas and correlations/ Module: Financial Markets Module leader: Prof. György Komáromi Written by László Földvári Industry Analysis I have choosen five companies from the Capital Goods sector / Autoparts Industry/ Nasdaq. The industry analysis is the essence and first step of getting a clearer view of the market players. We have to know the most important macroeconomical circumstances of industry as well. In

Correlation coefficient When we need to test the relationship between 2 quantitative variables‚ we use correlation coefficient and it measured by standardized covariance measure and investigates linear dependence. Before doing this‚ it is better to first make a scatterplot to check the outliers and linearity then get the idea about the nature and strength relationship. Next‚ we should calculate the r for correlation coefficient of variation‚ which measures the degree of linear dependence. r

analysis of these data. These statistics will include the mean‚ median‚ modal class and standard deviation‚ for both Life Expectancy and GDP per capita. In Section 3 we will find the regression line which best fits our data and the corresponding correlation coefficient r. It is natural to ask if there is a non-linear model‚ which better describes the statistical relation between GDP per capita and Life Expectancy. This question will be studied in Section 4‚ where we will see if a logarithmic relation

classified into two categories—changes in food prices and changes in fuel prices (which contain fuel‚ power‚ lubricants and light). Inferences and results were drawn out by running regressions on statistical data from 1975 onwards. The degree of correlation was useful in determining the dependency and testing the hypothesis.

The correlation between mercury concentrations‚ weight and length in various fish species are indicated in figures 4.20-21. Total mercury concentrations were determined in some fish species in both the dry and the wet season from the Weija dam. About 42 samples of fish which consisted of three (3) species were sampled in all. Among the species were tilapia zilli (n = 7). Tilapia mariae (n = 7) and Chrysichthys nigrodigitatus (n=7) all of which are consumable (edible) by human. The mean T-Hg concentration

Correlational Research “Correlation is a statistical technique that can show whether and how strongly pairs of variables are related” (Creative Research Systems‚ 2010). Correlation research method is used in scientific research to study the association and/or relationship between variables. When the association between two variables becomes correlation coefficient‚ it is being calculated through quantitative measure. The goal for using this method is to observe if one or more variables cause
