Correlação
by Rodrigo Lopez 03 Mar '19

03 Mar '19

Prezados, Estou tentando representar uma matriz de correlação e não consigo inserir o valor do coeficiente R e o valor P, ou a significância no mesmo plot. Gostaria que a metade superior (upper) mostrasse o R e a de baixo (lower) a significância. Não sei mexer muito com o corrplot.mixed. O máximo que consegui fazer foi inserir o coeficiente R e a significância juntos (ficaram sobrepostos). Alguma sugestão que como posso fazer? Ou mesmo deslocar a significância para não ficar sobreposta no valor do coeficiente *** library(readxl) seed <- read_excel("seed.xlsx") seed cor(seed, method = "pearson") M <- cor(seed, method = "pearson") library(corrplot) library(RColorBrewer) library(Hmisc) m <- rcorr(as.matrix(seed)) m P <- cor.mtest(seed, conf.level = .95) corrplot(M, p.mat = P$p, insig = "label_sig", sig.level = c(.001, .01, .05), pch.cex = 2, pch.col = "white", type = "upper", method = "color", order = "original", outline = "white", tl.col="black", tl.srt=45,diag = FALSE, addCoef.col = "black", col = colorRampPalette(c("blue", "yellow", "red"))(20)) Rodrigo R.

Modelos Mistos - Duvida sobre transformação/distribuição logistica
by Fernando Souza 01 Mar '19

01 Mar '19

Prezados Estou analisando um dado experimental utilizando a abordagem dos modelos mistos, através da função lme do pacote nlme. O dado no entanto não apresentou distribuição normal e tentativas como remoção de outliers, transformação foram infrutíferas. Tentei olhar se outra distribuição se ajusta melhor aos dados e encontrei que a distribuição logistica, se ajusta bem (Veja imagens abaixo), porém não sei como ajustar esse modelo utilizando a abordagem de modelos mistos. Visto que meus dados não são dados de proporção, como posso fazer para analisar tal dado? Desculpe a quantidade de informação fornecida abaixo, mas este é o mínimo que consegui organizar para ilustrar minha questão BiometriaAleit<-structure(list(Animal = structure(c(1L, 1L, 1L, 1L, 1L, 1L,

Problema com optim() em modelos não lineares
by ASANTOS 01 Mar '19

01 Mar '19

Prezados Membros, Estou tentando realizar a estimação dos coeficientes de um modelo não linear com a função optim(), mas só recebo a mensagem de erro: Error in optim(c(0.97, 0.32), function(a) f(a, x, yexp)) : função alvo em optim retorna um objeto de comprimento 11 ao invés de 1 Segundo o meu CRM: #Crio as variáveis x <- c(1 ,10, 20, 30, 40, 50, 60, 70, 80, 90, 100) y <- c(0.033823, 0.014779, 0.004698, 0.001584, -0.002017, -0.003436, -0.000006, -0.004626, -0.004626, -0.004626, -0.004626) #Especifico a função, que no meu caso é y ~ a4*exp(-x/a5) f = function(a,x,yexp) {yexp= a[1]*exp(-x/a[2]) } # Utilizando a otimização mod = optim(c(0.97, 0.32), function(a) f(a, x, yexp)) Alguém poderia me ajudar.
