This library serves as a companion to the publication “Understanding Jumps in High Frequency Digital Asset Markets”. However it can also be used independently for clustering high dimensional datasets and fitting an implied stochastic volatility model.
This library contains implementations of a few recent publications in the field of High Frequency Econometrics:
- Lee & Mykland Jump Test (Lee and Mykland 2012)
- Ait-Sahalia & Jacod Jump Test & Test for Jump Activity + variation estimation (Aït-Sahalia and Jacod 2012)
- Ait-Sahalia, Jacod & Li Jump Test (Ait-Sahalia, Jacod, and Li 2012)
- Pre-averaging approach ( Jacod et al. (2009), Jacod, Podolskij, and Vetter (2010) )
The methods can be used in a stand-alone fashion or when obtained from the Blockchain Research Center with additional functionalities.
The usage is pretty simple. First, install the package with devtools.
Note that this library is still experimental, s.t. no proper unit
testing or object classes have been implemented yet. In case of bugs
please report them and I will work on fixing them.

library(hf.econometrics)Now we can just load a suitable dataset and run the test statistics we desire. A sample dataset is provided to illustrate the necessary file structure.
# load the data
# currently, for this to work the data needs to be stored in "./data/raw/csv_dump/"
DT_list <- make_data("./data/raw/csv_dump/DT_sample.csv")
DT_split_list <- list("impute" = split_by_id(DT_list),
"no_impute" = split_by_id(DT_list))Once the data is loaded we can calculate the jump test statistic:
## get LM result ##
DT_LM_result_id <- jump_test(DT_split_list$no_impute, which_test = "LM_JumpTest")
## get AJL result ##
DT_AJL_result_id <- jump_test(DT_split_list$impute, which_test = "AJL_JumpTest")Finally, some processing can be made to denoise the jump statistic.
## Preprocess LM result ##
DT_jumps_crypto <- preprocess_jump_data(DT_LM_result_id, sign_level = 0.01)Ait-Sahalia, Yacine, Jean Jacod, and Jia Li. 2012. “Testing for Jumps in Noisy High Frequency Data.” Journal of Econometrics 168 (2): 207–22. https://econpapers.repec.org/article/eeeeconom/v_3a168_3ay_3a2012_3ai_3a2_3ap_3a207-222.htm.
