Right now XLstat offers only an annual subscription. I have the need to use XLstat and prefer not to use other software, but with a single, small project cannot justify $1395 for a couple days worth of analyses. I'd gladly pay for a month's subscription and maintain myself as a life-long customer, which would seem to be of benefit to XLstat, as well.
Yes, including for the upgrades (various "applied" versions, premium)
I am also a self-funded researcher who only uses statistical techniques intermittently.
we need monthly subscription
