1 Introduction 1.1 Authorisation and PurposeHerein we investigate the health development of East Asia and Pacific Region during the periodof 2001 to 2015. The data for the investigation has been taken from world bank. The researchteam is particularly interested in the relation of crude birth and death rate to the healthexpenditure of the region. Moreover, in this research we intend to study how crude birth anddeaths rate have varied across countries for last 15 years. In addition, the research intends tostudy the relation between growth in population of the region (the difference between crudedeath rate and crude birth rate) and health expenditure. Further, the relation betweenimmunization rate and crude birth rate is studied. The outcomes of the analysis have importance to government and planners. The analysis can beutilised for resource mobilisation to improve the health of the country. LimitationsThe analysis is limited to the region of East Asia and Pacific only. Scope For analysing the health of the region the present study is segregated into four groups. Initiallythe researcher evaluates the attributes using a one variable study. Box-plots and histograms areused to undertake a one-attribute study. In the second part two of variables are studies. inorder to undertake the two variable study box-plots were found to be best suited. In the nextsection the researcher has evaluated patterns in the relation between crude birth and deathrate. The countries of the region having similar death and birth rates have been groupedtogether. Finally, in the last section, growth in population of the region is related to healthexpenditure and birth rate to immunization rate. MethodologyQuantitative data got from world bank is used for the present analysis. The data pertains to thetime period of 2001 to 2015 and East Asia and Pacific Region.2 Data SetupIn order to undertake the analysis, the data file should be loaded into the R program. Thus thefirst line of the code requests the user to load the required data file. During the process ofrunning the first line of code a window pops up and the data file to be analysed is requested.The pre-processing of the data file also takes place when the data file is loaded. All missingvalues are tagged and the first row is taken as the header row. In the second stage the requiredlibrary files are loaded. In order to undertake the analysis certain library files are required. Thelibrary files are loaded in the second stage.
3 Exploratory Data Analysis3.1 One Variable Analysis3.1.1 One Variable Analysis – 1The crude death rate of the region per 1000 people in 2014 is studied as a one-variable analysis.In 2014 the average death rate was 6.37 with a standard deviation of 1.44 for every 1000people. The minimum and maximum death rate was 2.99 and 10 respectively in the region. Themedian death rate in 2014 was 6.16 for every 1000 people. From the analysis it can be seenthat the minimum and maximum death rates of the region are outliers.
