We will use the $2000 prize to write up our formal analysis for the grand prize in January. Our paper linked benthic ecosystem data over time with socio-economic dataContinue reading “EPA Coastal Data Contest Winners”

Sea Turtle Nesting Habits & Socioeconomic Indicators in R (part II)

I looked at nesting habits for greens, loggerheads, and leatherbacks to see if you could create linear regressions with population by county,Continue reading “Sea Turtle Nesting Habits in R”
