I don't think so. This page says it's an option in SPSS:
When I try running ANOVA using a recent version of PSPP, the only option
is to run Levene's test, it doesn't seem to produce Welch's test. This
page shows how to perform the test using a spreadsheet like Excel ot Calc:
Is there any way to run a Welch's ANOVA with PSPP? I have data that
failed the Levene's test for homogeneity of variances, and have been
advised to run a Welch's ANOVA, but have been unable to figure out how
to do that with PSPP (if it's possible at all) based on an online
search. The version I'm using is 0.10.4-g50f7b7.

functions on fire in a copy of Orion.
I watched C-Sharp glitter in the dark near a programmable gate.
All those moments will be lost in time, like Ruby... on... Rails... Time for Pi.
