[R] using extremes - extreme value analysis for low (minimum) temperature
Hello, I am trying to answer the question: "What is the probability of a certain day's low forecast (of 21) being the month's overall low?" I decided to attempt it in R Searching pointed me to extreme value analysis. I created a csv file of the last 8 years lows for the month: year month's low 2009 10.04 2010 18.493 2011 7.547 2012 15.008 2013 19.283 2014 9.508 2015 2.55 2016 20.1 I loaded "extremes" install.packages("extRemes") library(extRemes) I successfully loaded the csv file. I initially started with fitting to a Gumbel fit2 <- fevd(PeakingLowTemp,FebruaryEVA,type="Gumbel") Now for my question - unfortunately the examples I am finding all deal with maximums - meaning maximum high temps and probability of exceeding and maximum rainfall and probability of exceeding I need to fit the lows (minimums) and calculate the probability of being less than a temp. Can you help guide me with the remainder of my setup Thanks!! [[alternative HTML version deleted]]
