Answer Format 1. Send me your new data file via blackboard 1 BADM 735 - Comparative Economics – Assignment Five (C) Creating Scatter Diagrams and Correlation Matrix Using Stata A scatter diagram plots two variables taken from the same point in time for different countries to show relationship between the two variables. For better understanding of scatter plots watch the video contained in the link below https://www.youtube.com/watch?v=30LcZqRfPRY
According to the text, economic outcomes measured by economic growth is affected by a number of factors. Also, hundreds of empirical studies on economic growth across countries have highlighted the correlation between economic growth and a variety of variables. a) Using your data from Assignment 3 B: Construct a scatterplot, in stata, that shows the relationship between: measure of Investment) expenditure (% of GDP) c growth and Inflation, consumer prices (annual %) (% of GDP) GDP) **Economic growth is our dependent variable; all the other variables are independent**
The graphs below should serve as a guide. According to the graph, there appears to be a positive correlation between Economic Growth and Investment. The Correlation coefficient is about 0.154 which confirms a weak positive correlation between the two variables. https://www.youtube.com/watch?v=30LcZqRfPRY 2 STATA COMMANDS FOR SCATTER PLOTS STEP 1: USING THE COMMAND WINDOW INSTALL “asdoc” AS SHOWN BELOW “asdoc” is an add-on to stata that allows you to produce nicely
formatted tables tables in stata STEP 2: USING THE YOUR DO-FILE YOU CAN CREATE SCATTER PLOTS AS SHOWN BELOW -Because a scatter diagram plots two variables or shows the relationship between two variables. - Fit a line in the scatter plot independent variable ( as you can see economic growth comes before trade) Please note also that you have to run the same command for all the other relationships; for example to show the relationship between economic growth and inflation you run: twoway (scatter Economic_Growth Inflation) (lfit Economic_Growth Inflation) STEP 3: EDITING, FORMATTING AND SAVING YOUR GRAPH It is important you edit your graph to conform to the scatter plot shown above. The video
contained in the link below should help you edit and format your graph. https://www.youtube.com/watch?v=PWFZ_-eQd8I&t=296s STEP 4: COPY YOUR GRAPHS INTO WORD https://www.youtube.com/watch?v=PWFZ_-eQd8I&t=296s 3 b) Create a correlation matrix table that shows pairwise correlation coefficients between the following variables (without significance test): GDP growth (annual %), Gross capital formation (% of GDP), General government final consumption expenditure (% of GDP), Trade (% of GDP), Inflation, consumer prices (annual %), Foreign direct investment, net inflows (% of GDP), Population, total, and Total natural resources rents (% of GDP) For better understanding of correlations watch the video contained in the link below https://www.youtube.com/watch?v=jf-SIOFUuEo
STATA COMMANDS FOR CORRELATION MATRIX USING THE YOUR DO-FILE YOU CAN GENERATE THE CORRELATION MATRIX AS SHOWN BELOW A sample shot of a correlation matrix The 0.154 shows the strength of the relationship between Economic growth and Investment https://www.youtube.com/watch?v=jf-SIOFUuEo 4
c) Compare the correlation matrix with the scatter graphs. See the example below According to the graph, there appears to be a positive correlation between Economic Growth and Investment. The Correlation coefficient is about 0.154 which confirms a weak positive correlation between the two variables. ***Please do not hesitate to call or email if you need assistance***
