This vignette describes in detail how an analysis can be configured further by providing more custom data. The configurations are not required but, in case additional information is available, may help you improve the accuracy of your results.
In order to keep this vignette concise, we assume the following has been set up:
r2dii.climate.stress.test
. Note that this may require
installing additional packages. You will be prompted to install these in
case any are missing.In order to keep this vignette concise, we assume that you have successfully completed all preparation steps described in the vignettes Set up project directories.
Financial data provide several financial indicators on the company level. If data is available you can replace our standard financial data set with a data set holding your financial information on the companies you included in the analysis.
The data that needs to be created is a csv file named
prewrangled_financial_data_stress_test.csv
to replace the
default prewrangled_financial_data_stress_test.csv
file. It
holds the columns:
company_name
: character, holding the name of analysed
companies.company_id
: numeric, the id of company as classified by
asset resolution. For loans workflow a placeholder value will be
used.corporate_bond_ticker
: character, holding the
identifier. Will be NA for loans workflow.pd
: numeric, holding the probability of default per
company. Needs to be equal to or larger than 0 and smaller than 1.net_profit_margin
: numeric, holding the
net_profit_margin per company. Needs to be larger than 0 and equal to or
smaller than 1.debt_equity_ratio
: numeric, holding the ratio of
outstanding debt to the company’s equity value. This is the company’s
financial leverage. Needs to be larger than 0.volatility
: numeric, holding the volatility of asset.
Needs to be equal to or larger than 0.NOTE: No column, except for corporate_bond_ticker, may have missing values.
In column company_name
include all unique company names
from Loans_results_company.rda
, which you generated in prepare
loans inputs. Running the following code will generate a dataset
with all required columns. Column campany_name
includes the
unique company names, company_id
includes a placeholder id,
all other columns are empty.
library(readr)
library(r2dii.climate.stress.test)
loans_results_company_file_path <- file.path("/example_project/project_specific_input", "Loans_results_company.rda")
validate_file_exists(loans_results_company_file_path)
data <- readr::read_rds(loans_results_company_file_path)
fin_companies <- data %>%
dplyr::select(company_name) %>%
dplyr::distinct() %>%
dplyr::mutate(
company_id = 999,
corporate_bond_ticker = NA,
pd = NA,
net_profit_margin = NA,
debt_equity_ratio = NA,
volatility = NA
)
readr::write_csv(fin_companies, file.path("/example_project/project_agnostic_input", "prewrangled_financial_data_stress_test.csv")) # NOTE that this will overwrite financial data currently stored at the location if available
You can now open this file in a tool of your choice and fill in
values for the remaining variables. For column company_id
keep using a placeholder value (999 in example) and leave entries for
corporate_bond_ticker
as NA. Please make sure to save the
result as a csv file again.
Before including the file in your analysis you may want to validate that your file complies with requirements concerning structure and content. You may verify by executing the following lines of code. You will receive warning/error messages in case problems are detected.
library(readr)
library(r2dii.climate.stress.test)
financial_data_path <- file.path(
"/example_project/project_agnostic_input",
"prewrangled_financial_data_stress_test.csv"
)
validate_file_exists(financial_data_path)
data <- readr::read_csv(financial_data_path)
check_financial_data(financial_data = data, asset_type = "loans", interactive_mode = TRUE)
In order to make sure your version of
prewrangled_financial_data_stress_test.csv
is used in the
analysis place it in
project_agnostic_input/
as set up in Set up project directories. If the respective dataset as provided by 2DII already exists there make sure to replace it with your custom file.
You can now run the stress test as described in vignette Run stress test.
