File size in JASP – What determines the file size of analyses?
Dear JASP community,
I kindly ask, what determines the file size of JASP files when having run and saved analyses? I have managed to reach a file size of 1.15 GB with a relatively small dataset (10 rows, 22 variables).
The analyses contain:
2 Bayesian linear regressions (sampling method BAS default), 2 frequentist linear regressions, 2 PCAs, 2 EFAs, 2 Bayesian correlations, 1 Bayesian paired-samples t-test (student), 2 descriptive statistics, and 1 Bayesian single-test reliability (MCMC sampling, 500 burn-in, 50,000 iterations, thinning 1, no. chains 3, rhat, and traceplots). The method listed at the end, MCMC sampling makes always GBs of file size under these settings, especially the traceplot seems to be take much space when trying to depicting it in another software.
Does anyone know why MCMC samples of 500 burn-in and 500,000 create at least 1 GB or more GBs of data file in JASP whereas they are that easy to handle and safe in R where they are just of a few KBs? It is just an assumption that it is this procedure since it is congruent with other GB-heavy data files that contain the same procedure. Loading and opening the file in JASP also requires significantly more time than all other files that are in the area of a few MB or even KB range. I would be that happy about an answer!
