Hooray! Our paper (led by Emily Nightingale) is out. Inferring the regional distribution of Visceral Leishmaniasis incidence from data at different spatial scales. w/ @grahammedley.bsky.social and others. www.nature.com/articles/s43...
Panel plot. a) shows estimated coefficients from models with and without a spatial random field. NDVI is positive for both. LST is strong negative until you add a field. b) predicted rate of VL. High in the north of Bihar, India. c) The fitted random field. High in North Bihar as well.
