One of the highlights of the festival was the food fair, where students and faculty members had set up stalls offering a wide range of delicious cuisines. From spicy street food to sweet desserts, the options were endless, and everyone had a great time savoring the flavors.

The festival also saw some friendly competitions, with students vying for top honors in various categories. The winners of the different events were announced, and prizes were distributed to the winners. ariel academys secret school festival gallery hot

Ariel Academy's Secret School Festival was an unforgettable experience, showcasing the school's rich talent, creativity, and school spirit. The event was a resounding success, and everyone left with cherished memories and a sense of pride in their school. One of the highlights of the festival was

The festival, which was held in the school's sprawling courtyard, was a kaleidoscope of colors, music, and laughter. The atmosphere was electric, with students showcasing their hidden talents and passions through various performances, exhibitions, and activities. The winners of the different events were announced,

As with birth rates, we use data for 4 categories of countries from 1990 to 2015 (100 observations total). We have two explanatory variables, AGE and Y, where AGE is defined as the percentage of the population aged over 65 and Y is per capita GDP.

After eyeballing the scattergrams, we test the following functional form:

d = (minY^a)/Y^a * (1/AGE^g)

Where minY is the constant equal to the smallest value of Y in the series.

Logarithmic transformation gives:

ln(d) = ln(minY^a) – a*ln(Y) – g*ln(AGE)

which we test on the data using OLS. Here are the results:

Adjusted R square: 75.191

Intercept coefficient: 7.37384
t-Stat: 20.4011

Y coefficient: -1.01444
t-Stat: -13.1059

AGE coefficient: 2.0097
t-Stat: 11.5208

The estimated intercept is a good, but not perfect, approximation of ln(minY^a)

Here are the fitted against actual values of the scattergram for death rate against per capita GDP:

While the results are not as good as with the birth rates calculations, it is nevertheless a good enough fit and the explanatory variables have a strong enough confidence factor to be usable in our estimations.

We begin by examining the scatter of data for 100 observations of per capita GDP and per capita emissions for 4 categories of countries, over 25 years (1990 – 2015).

The scatter suggests a cubic functional form, so we test:

GHG = a + b*Y + c*Y^2 + d*Y^3

where GHG are per capita emissions of GHG, and Y is per capita GDP.

The results from OLS regression are:

Adjusted R square: 0.980438073

coefficient a: 1090
t-stat a: 3.06

coefficient b: 0.709310153
t-Stat b: 8.241453

coefficient c: -0.0000047025
t-Stat c: -1.01233

coefficient d: -0.000000000105314
t-Stat d: -1.47005

While the t-scores on the squared and cubed terms are low, the number of observations are also limited.

Here is the plot of the fitted against actual values:
