Cleaning Data

Creating Linear regression

In this chunk i will be creating a nultiple linear regression modeling Aids related deaths as the funtion of People living with HIV and New HIV infections.

# based on the output of my model my equation is Death(All ages) = 1995 + (0.0135 x Total PLHIV) + ( 0.2493 x New Infection)
# This means that for every 1 additional new HIOV infection, the prediction is that approximately 0.25 additional deaths will occur, keeping the total number of people living with HIv constant.

##Plotting results

# Spliting the plotting area into 2 rows and 2 columns
par(mfrow = c(2, 2))

# Generate the diagnostic plots
plot(model)

# Reset plotting area back to 1x1
par(mfrow = c(1, 1))

Creating Plot

ggplot(Clean_Data, aes(x = data_people_living_with_hiv_total, 
                       y = data_aids_related_deaths_all_ages, 
                       color = country_region)) +
  geom_point(alpha = 0.6) +
  scale_color_brewer(palette = "Set1") + # Professional non-default palette
  labs(title = "AIDS Deaths vs. HIV Prevalence by Region",
       color = "Region") +

I had to clean the data set first by using the clean names function which which i got form the Janitor package to standardize the column names of my data set putting it into a machine friendly format. Then i had to use mutate to create a country_region region for my final plot which required an installation of the countrycode package. After this due to recieving errors while trying to create my final plot, i had to research why it was happening and post research i found out that my data set had older names in my csv. This required me to filter using the is.na funtion, as well as mutate again to correct those errors. My final visualization represents Aids death pitted against HIV prevalence by region utilizing people living with HIV and Aids related deaths for all ages. I already knew Africa held the title for both but seeing the visualization put things more in perspective for me. I wanted to see the statisitics in children but that was also providing me with errors but after turning in this assignments i will be researching this as well.
