NDMA Data Pre processing

The following are steps undertaken for deidentifying NDMA data. The data is dis aggregated per county for all 23 counties - ASAL. The information covers the years of 2000 - 2020, where data prior to 2016 was stored in a different database (REWAS) and data from 2016 henceforth in the new database (DEWS). In each county data set workbook there are 6 different sheets:

HHA REWAS, HHA DEWS, KIA REWAS, KIA DEWS, MUAC REWAS, MUAC DEWS

The process involves inspecting individual sheets for each data set, dropping P.I.I columns, and then writing all the sheets to a single workbook - Embu.

library(openxlsx)

file_path <- "C:/Users/AAH USER/Downloads/Embu.xlsx"

# Read the specific sheet into a data frame
hha_rewas_data <- read.xlsx(file_path, sheet = "HHA REWAS")

There are no P.I.I columns in this particular sheet so we save it to a new workbook and populate the rest of the sheets sequentially to the same Embu workbook after relevant pre processing steps have been taken.

# Define the path for the new Excel workbook
new_file_path <- "C:/Users/AAH USER/OneDrive - Action Against Hunger USA/Documents/NDMA_DeIdentified/Embu.xlsx"

# Create a new workbook
wb <- createWorkbook()

# Add the HHA-REWAS data to the new Embu workbook
addWorksheet(wb, "HHA REWAS")
writeData(wb, "HHA REWAS", hha_rewas_data)

# Save the new workbook
saveWorkbook(wb, new_file_path, overwrite = TRUE)

2. HHA DEWS

The geocoordinates in the HHA dataset represent household coordinates, we will mask them (random displacement) using the Haversine Formula to randomly distribute a point around a central coordinate within a radius of 2.5 KM and drop other P.I.I.s.

library(openxlsx)

file_path <- "C:/Users/AAH USER/Downloads/Embu.xlsx"

# Read the specific sheet into a data frame
hha_dews_data <- read.xlsx(file_path, sheet = "HHA DEWS")

The dataset contains household coordinates in columns “Lat” and “Long” which are considered P.I.I’s so we mask the coordinates, verify by plotting a histogram of the distribution of displacement distances of the original and displaced coordinates to establish uniformity.

We check for and deal with outliers if any in the “Lat” and “Long” columns

# Verify the dataset
summary(hha_dews_data$Lat)
##    Min. 1st Qu.  Median    Mean 3rd Qu.    Max.    NA's 
##  -1.038  -0.675  -0.461  -0.529  -0.453   0.000    3365
summary(hha_dews_data$Long)
##    Min. 1st Qu.  Median    Mean 3rd Qu.    Max.    NA's 
##    0.00   37.42   37.64   32.98   37.74   37.90    3365

There seems to be erroneous entries. 3365 rows also dont have entries for coordinates.

# Replace (0,0) coordinates with NA only in the Lat and Long columns
hha_dews_data$Lat[hha_dews_data$Lat == 0 & hha_dews_data$Long == 0] <- NA
hha_dews_data$Long[hha_dews_data$Lat == 0 & hha_dews_data$Long == 0] <- NA

# Calculate the mean for Lat and Long, ignoring NA values
lat_mean <- mean(hha_dews_data$Lat, na.rm = TRUE)
lon_mean <- mean(hha_dews_data$Long, na.rm = TRUE)

lat_sd <- sd(hha_dews_data$Lat, na.rm = TRUE)
lon_sd <- sd(hha_dews_data$Long, na.rm = TRUE)

# Calculate Z-scores
hha_dews_data <- hha_dews_data %>%
  mutate(lat_z = (Lat - lat_mean) / lat_sd,
         lon_z = (Long - lon_mean) / lon_sd)

# Set threshold for identifying outliers
threshold <- 3  # Common threshold for Z-scores

# Replace outliers with NA
hha_dews_data <- hha_dews_data %>%
  mutate(Lat = ifelse(abs(lat_z) > threshold & !is.na(lat_z), NA, Lat),
         Long = ifelse(abs(lon_z) > threshold & !is.na(lon_z), NA, Long))

# Remove the Z-score columns 
hha_dews_data <- hha_dews_data %>%
  select(-lat_z, -lon_z)

# Verify the dataset
summary(hha_dews_data$Lat)
##    Min. 1st Qu.  Median    Mean 3rd Qu.    Max.    NA's 
##  -1.038  -0.701  -0.584  -0.604  -0.455  -0.317    3726
summary(hha_dews_data$Long)
##    Min. 1st Qu.  Median    Mean 3rd Qu.    Max.    NA's 
##    0.00   37.42   37.64   32.98   37.74   37.90    3365

400 rows in total are affected by the outlier and are replaced with NAs, bringing the total to 3726 NAs. We proceed to mask the coordinates.

# Create backup columns for original coordinates
hha_dews_data$Original_Lat <- hha_dews_data$Lat
hha_dews_data$Original_Long <- hha_dews_data$Long

# Function to generate random displaced coordinates with uniform distance distribution
mask_coordinates_uniform <- function(lat, lon, radius_km) {
  R <- 6371  # Earth radius in kilometers
  
  # Random bearing angle (in radians)
  bearing <- runif(1, 0, 2 * pi)
  
  # Random distance uniformly sampled from [0, radius_km]
  rand_dist <- runif(1, 0, radius_km) / R  # Uniformly sampled distance in radians
  
  # Convert original coordinates to radians
  lat_rad <- lat * pi / 180
  lon_rad <- lon * pi / 180
  
  # Calculate new latitude (in radians)
  new_lat <- asin(sin(lat_rad) * cos(rand_dist) + 
                    cos(lat_rad) * sin(rand_dist) * cos(bearing))
  
  # Calculate new longitude (in radians)
  new_lon <- lon_rad + atan2(sin(bearing) * sin(rand_dist) * cos(lat_rad),
                             cos(rand_dist) - sin(lat_rad) * sin(new_lat))
  
  # Convert back to degrees
  new_lat <- new_lat * 180 / pi
  new_lon <- new_lon * 180 / pi
  
  return(c(new_lat, new_lon))
}

# Set displacement radius in kilometers
radius_km <- 2.5  

# Generate masked coordinates for each row using the modified function
masked_coords <- t(apply(hha_dews_data, 1, function(row) {
  mask_coordinates_uniform(as.numeric(row["Original_Lat"]), as.numeric(row["Original_Long"]), radius_km)
}))

# Replace the original Lat and Long columns with the masked coordinates
hha_dews_data$Lat <- masked_coords[, 1]
hha_dews_data$Long <- masked_coords[, 2]

We then evaluate the distribution of the displacement distances before dropping the original coordinates by plotting a histogram.

# Calculate displacement distances (in kilometers) as before
displacement_distances <- distHaversine(
  cbind(hha_dews_data$Long, hha_dews_data$Lat),  # Masked coordinates
  cbind(hha_dews_data$Original_Long, hha_dews_data$Original_Lat)  # Original coordinates
) / 1000  # Convert meters to kilometers

# Add displacement distances to the dataset for further analysis
hha_dews_data$Displacement_Distance <- displacement_distances

# Plot: Histogram of displacement distances
ggplot(hha_dews_data, aes(x = Displacement_Distance)) +
  geom_histogram(binwidth = 0.1, fill = "skyblue", color = "black") +
  labs(title = "Distribution of Displacement Distances",
       x = "Displacement Distance (km)", y = "Count") +
  theme_minimal()
## Warning: Removed 3726 rows containing non-finite values (`stat_bin()`).

There are no significant peaks or valleys in the histogram, suggesting that the displacements are indeed more uniformly distributed, as intended.

We then drop the original coordinates column leaving only the masked coordinates columns. We also drop other PII’s which are the “HouseholdName”, “HouseHoldHead”, and “RespondentName”.

# Drop the specified PII columns along with original coordinates
hha_dews_data <- hha_dews_data %>%
  select(-c(Original_Lat, Original_Long, Displacement_Distance, HouseholdName, HouseHoldHead, RespondentName))  

# Check the updated dataset
head(hha_dews_data)

We also have to ensure that the “InterviewDate” column is parsed correctly as a date before saving the worksheet to the new workbook.

# Convert the numeric date to Date format

We also have to ensure that the “InterviewDate” column is parsed correctly as a date. The row values are displaced to the “SufferedIllnesses” column. We align this and proceed to parse the date correctly.

# Create a mask for rows to modify
rows_to_modify <- which(muac_dews_data$Year %in% 2016:2019)

# Ensure the columns being shifted are correctly specified
# We will create an index to specify which columns to shift
shift_columns <- c("MUAC_Color", "AgeInMonths", "LiveInHousehold", 
                   "SufferedIllnesses", "InterviewDate", 
                   "DivisionID", "CountyID", "SiteID", "LivelihoodZoneID")

# Create an empty data frame for the shifted values
shifted_values <- muac_dews_data[rows_to_modify, shift_columns]

# Replace the values in the original DataFrame with NA in the selected rows
muac_dews_data[rows_to_modify, shift_columns] <- NA

# Move the values one column to the right
for (i in seq_along(shift_columns)[-length(shift_columns)]) {
  muac_dews_data[rows_to_modify, shift_columns[i + 1]] <- shifted_values[[i]]
}
library(lubridate)
# Ensure the column is numeric
muac_dews_data$InterviewDate <- as.numeric(muac_dews_data$InterviewDate)
# Convert the Excel serial date to R Date
muac_dews_data$InterviewDate <- as.Date(muac_dews_data$InterviewDate, origin = "1899-12-30")
