// This do-file is an example of hwo you could ste up ana analysis of BIS data
// each STEP could be saved as a separate do-file if preferred
// you can run a do-file from within a do-file using the command: do "dofile_name.do"



********************************************************************************
* STEP 0: Set directories etc.
********************************************************************************
* Set working directories
// Locations where any files for this project will be saved
// Its easier to type these out only once, at the beginning of the analysis
global rawdataloc "C:\Project\Raw data"
global analysisloc "C:\Project\Analysis files"
global cleandataloc "C:\Project\Clean data"
global outputloc "C:\Project\Tables and figures"


* Get the current date
// This creates a macro with today's date in the format YYYYMMDD
global date: display %tdCCYYNNDD date("`c(current_date)'","DMY")





********************************************************************************
* STEP 1: Data cleaning
********************************************************************************
* Create a single, clean dataset for analysis
** Open dataset of demographics/baseline charactersitcs
cd "$rawdataloc"
use "demographics_data", clear

** Add data from timepoint 1
cd "$rawdataloc"
merge 1:1 bisid using "timepoint1_data"

// Make sure variable names don't clash with variable names in other datasets
// E.g. the date that questionnaire 1 was completed might be called 'date'
// This should be renamed to 'date1' so it doesn't clash with the date that questionnaire 2 was completed


** Add data from timepoint 2
cd "$rawdataloc"
merge 1:1 bisid using "timepoint2_data"


// Insert any other data clenaing steps here


// If you need to add additional datasets later on, you can do this here


** Save cleaned data
// It's good practice to save this dataset with today's date
// This way, if you make any changes to your analysis later on, 
// you can always come back to a previous version of your data
cd "$cleandataloc"
save "cleandata_${date}", replace




// If you have finalised your data cleaning, you can comment out this 
// entire STEP using: /* and */





********************************************************************************
* STEP 2: Analysis
********************************************************************************
** Open the clean data
// You will need to update this with the most up-to-date dataset you have
cd "$cleandataloc"
use "cleandata_20201009", clear


// Perform any analysis steps here


** Save figure
// create your graph using e.g. twoway ...
cd "$outputloc"
graph export "figure1.png", replace
