long shot, but does anyone have icelandic poppy seeds I could buy in the carrboro area? I would love some locally-successful poppies in white/peach/orange colors (like the champagne bubbles variety) to start over winter! #carrboro #chapelhill #gardening
Help me @ggwash and others! I'm looking for examples of road widening projects that failed to reduce congestion (lol) for a ~thesis~ project. State DOT websites just want to show me projects that are currently approved or in progress, but I'm looking for road expansions that were *completed* maybe 2016-2018, so there would have been several years of traffic response to the expansion pre-COVID. Any MD/VA ideas?
does anyone in Carrboro need MULCH? I accidentally came into possession of an enormous pile of hardwood woodchips…
Does anyone have any readings about evaluating the quality of matches when using a matching approach to causal inference (ideally k-nearest neighbor w/ Mahalonobis distance, not PSM)? How to double-check that your matching is at least somewhat adequately accounting for confounders that go along with self-selection into the treatment? #causalinference #impactevaluation #statistics
BONUS for some kind of placebo test - match a subset of the control pop. (a "pseudo-treatment") to other controls.
