Introduction
HDI: a summary measure of human development
HDI measures three basic dimensions of human development:
- a long and healthy life, as measured by life expectancy at birth
- knowledge, as measured by the adult literacy rate
- standard of living, as measured by GDP per capita
HDI has had a significant impact on drawing the attention of governments, corporations and international organizations to aspects of development that focus on the expansion of choices and freedoms, not just income.

Model specificationHDI = β1 + β2* GDP + β3*EDU + β4*LIE + u
HDI: dependent variable
GDP (Gross Domestic Product): dependent variable
- Y = C + I + G + NX
- GDP per capita = Y/ Population
Educational attainment (EDU): dependent variable
- represented by the literacy rate
- considered as a crucial measure of a region's human capital since literacy increases job opportunities and access to higher education.
Life expectancy (LIE): dependent variable
- the average number of years a human has before death
- an important measure in its own right and can be a proxy measure for many other issues such as healthcare, wealth, opportunities, and education

Results
Errors in the model:
- Multicolinearity:
+ happens when there is a functional relationship among independent variables.
+ all coefficients are significant
=> don’t need to worry about this error

EconometricsPage 16
Results- Heteroscedasticity: to check this error, Park-test is used
lnu^2 = β1 + β2*EDU
^Lne_sp= 22.0571 -42.157*EDU
H0 : β2 = 0 Heteroscedascity does not exist.
H1 : β2 ≠ 0 Heteroscedascity exists
From the table, P-value of β2> 0.05
=> β2 is not significant at 0.05
=> do not reject H0
=> there is no heteroscedascity

- Autocorrelation: to check this error, use The Breusch-Godfrey (BG) test
H0 : no autocorrelation
H1: autocorrelation exists
BG-statistic: 1.204509 < X 2p=1 = 3.84146
(α=0.05).
=> do not reject H0
=> no autocorrelation

Results
Discussion
^HDI= - 0.021 + 0.3214 * GDP + 0.384 * EDU + 0.3144 * LIE
+ β2, β3 and β4 at 5% level of significance, their P-value are all < 0.05
=> GDP, EDU, LIE have significant impact on HDI Index
+ R2 = 0.996975 => more than 99% of the variation of HDI index can be explained by GDP, LIE, EDI indexes
=> very high level of fit between the regression line and the data provided.

Conclusions and suggestions
Conclusions:
With the lowest CV, linear_linear was the best model
All the coefficients are significant shows a significant impact of EDU, LIE, and GDP indexes on HDI index
With positive sign of coefficients, there is a positive relationship between HDI indexes and the other three listed indexes.
Suggestions:
Invest more in education
Provide more health care service with good quality
Apply suitable economic development strategy to increase GDP
