From cb0ec2c5ffe7b519a1dfb3fddecc3fbfdaa085dd Mon Sep 17 00:00:00 2001 From: Debian Science Maintainers Date: Wed, 11 Jan 2023 23:51:04 +0000 Subject: [PATCH] Loosen tolerances on some tests on i386 and xfail a test that fails for not producing ConvergenceWarning. Failure logs: test_smoothing https://buildd.debian.org/status/fetch.php?pkg=statsmodels&arch=i386&ver=0.9.0-3&stamp=1567157609&raw=0 test_multivariate_switch_univariate https://buildd.debian.org/status/fetch.php?pkg=statsmodels&arch=i386&ver=0.12.0-1&stamp=1599693472&raw=0 As it only fails on i386 and isn't far wrong, I suspect different rounding due to x87 excess precision Author: Rebecca N.
