In mhkhan27/illuminate: Weighted survey analysis

illuminate

Overview

illuminate is designed for making the data analysis easy and less time consuming. The package is based on tidyr, dplyr,srvyr packages. Most common functions are-

Installation

You can install the development version from GitHub with:

# install.packages("devtools")
devtools::install_github("mhkhan27/illuminate")

1. Read and write file

• read_sheets() read all sheet in an excel file and makes sure that data stores in appropriate data type.
• write_formatted_excel() write formatted excel.

2. Data cleaning

• outlier_checks()
• others_checks()
• survey_duration_from_audit()
• logical_checks()

3. Creating cleaning log

4. Implementing cleaning log

• implementin_cleaning_log() Once you have raw data and cleaning log,you can use implementin_cleaning_log() function to get the clean data. Note that you need at least three column in your cleaning log to run the function which are - 1. uuid, 2. question name which must be matched with the data set and 3- a column specifying the what kind of change you are expecting. It is recommend to run the check_cleaning_log() beforehand which checks the cleaning log accuracy. See the documentation with ?check_cleaning_log() and ?implementing_cleaning_log() for more details.

EXAMPLE:: Implementing cleaning log

Step 1:: Call libraries and read data

library(illuminate)
library(tidyverse)

cleaning_log <- read.csv("data/01_implementing_cleaning_log/cleaning_log.csv")
data <- read.csv("data/01_implementing_cleaning_log/data.csv")

Step 2:: Check the cleaning log

check_cleaning_log() will flag any potential issue(s) within the cleaning log. If there is no issue then there will be a messege saying no issues in cleaning log found

check_cleaning_log(df = data,
                   df_uuid = "X_uuid",
                   cl = cleaning_log,
                   cl_change_type_col = "changed",
                   change_type_for_change_response = "Changed",
                   cl_change_col = "question.name",cl_uuid = "X_uuid",cl_new_val = "new.value"
)

Step 3:: Getting the clean data from cleaning log

implement_cleaning_log() will apply the cleaning log on raw data and will provide the clean data.

clean_data <- implement_cleaning_log(df = data,
                       df_uuid = "X_uuid",
                       cl = cleaning_log,
                       cl_change_type_col = "changed",
                       change_type_for_change_response = "Changed",
                       change_type_for_blank_response = NA,
                       change_type_for_no_change = c("No_Changes","Confirmed"),
                       change_type_for_deletion = c("NOT_ANS_PELASE_REMOVE", "From must be deleted"),
                       cl_change_col = "question.name",cl_uuid = "X_uuid",cl_new_val = "new.value"
                       )

5. Data Analysis

• survey_analysis() calculate the weighted mean/proporation/median and unweighted count for all existing variable is the dataset.

EXAMPLE :: Survey analysis

Step 0:: Call libraries

library(illuminate)
library(tidyverse)
library(purrr)
library(readxl)
library(openxlsx)
library(srvyr)

Step 1:: Read data

Read data with read_sheets(). This will make sure your data is stored as appropriate data type. It is important to make sure that all the select multiple are stored as logical, otherwise un weighted count will be wrong. It is recommended to use the read_sheets() to read the data. use `?read_sheets() for more details.

read_sheets("data/data.xlsx",data_type_fix = T,remove_all_NA_col = T,na_strings = c("NA",""," "))

The avobe code will give a dataframe called data_up

Step OPTIONAL:: Preaparing the data

ONLY APPLICABLE WHEN YOU ARE NOT READING YOUR DATA WITH read_sheets()

# data_up <- read_excel("data/data.xlsx")
data_up <- fix_data_type(df = data_up)

Step 2:: Weight calculation

To do the weighted analysis, you will need to calculate the weights. If your dataset already have the weights column then you can ignore this part

Read sampleframe

read_sheets("data/sampling_frame.xlsx")

This will give a dataframe called sampling frame

weights <- data_up %>% group_by(governorate1) %>% summarise(
  survey_count = n()
) %>% left_join(sampling_frame,by =c("governorate1"="strata.names")) %>% 
  mutate(sample_global=sum(survey_count),
         pop_global=sum(population),
         survey_weight= (population/pop_global)/(survey_count/sample_global)) %>% select(governorate1,survey_weight)

Add weights to the dataframe

data_up <- data_up %>% left_join(weights)

Step 3.1:: Weighted analysis

overall_analysis <- survey_analysis(df = data_up,weights = T,weight_column = "survey_weight",strata = "governorate1")

Step 3.2:: Unweighted analysis

columns_to_analyze <- data_up[20:50] %>% names() 
overall_analysis <- survey_analysis(df = data_up,weights = F,vars_to_analyze = columns_to_analyze )

Step 3.3:: Weighted and disaggregated by gender analysis

Use ?survey_analysis() to know about the perameters.

# dummy code. Please define the name of the columns which you would like to analyze. Default will analyze all the variables exist in the dataset. 

analysis_by_gender <-  survey_analysis(df = data_up,weights = T,weight_column = "survey_weight",vars_to_analyze = columns_to_analyze,
                                       strata = "governorate1",disag = c("va_child_income","gender_speaker"))

Step 4:: Export with write_formatted_excel()

You can use any function to export the analysis however write_formatted_excel() can export formatted file. See the documentation for more details

write_list <- list(overall_analysis ="overall_analysis",
                   analysis_by_gender ="analysis_by_gender"
)

write_formatted_excel(write_list,"analysis_output.xlsx",
                      header_front_size = 12,
                      body_front = "Times")
