This post is actually about replicating the figures in Otto and Day: A Biologist's Guide to Mathematical Modeling in Ecology and Evolution. The ecological detective: confronting models with data. In exchange for mathematical tools, finance provides ecology with a wealth of data. Inspired by (but independent of) ecology. In the wake of Steve Hubbell's very influential application of a neutral population genetics model to ecology, ecologists seem increasingly keen to develop “neutral” or “null” models for all sorts of ecological phenomena. The figures I'm interested in for this post are M <- matrix( c(20/33, -2/11, 8/33, 46/33) , ncol=2 ) A <- eigen (M)$vectors D <- diag(eigen(M)$values) N <- array( dim=c(11, 2) ) n0 <- matrix( c(2,1) ) N[1,] <- n0 for(i in 2:11){ N[i,] <- A %*% D^(i-1) %*% solve(A) %*% n0 } N <- as.data.frame(N). Other good resources are Logistic Regression Models (Chapman & Hall/CRC Texts in Statistical Science) and Modern Regression Techniques Using R: A Practical Guide . First, he explored the logistic map x_{t + 1} = r x_t(1 - x_t) May and colleagues make these connections precise by building analytic models for toy financial systems and then using their experience and tools from theoretical ecology to solve these models. Further, the cross-fertilization is not one-sided. Read more MCED, which stands for Modelling Complex Ecological Dynamics, is a textbook presenting an overview in approaches and applications in ecological modeling. Lamar Smith (R-Tex.) offered up a reheated stew of isolated factoids and sweeping generalizations about climate science to defend the destructive status quo. Students and academics receive low priority only because most universities provide courses and workshops on using R, or statistics and data analysis courses that use R for their exercises. [] The title was CliMathematics: Models, data, structures. In a recent op-ed for The Post, Rep. Ecological Models and Data in R by Ben Bolker is a great book for learning applied ways to manipulate data, formulate analyses, and generate graphics in R. In practice, this usually And in ecology, the world often is overdetermined, by which I mean simply that many different combinations of processes are sufficient to generate the observed data, with no one of them being necessary. Training ecologists to think with uncertainty in mind.
