similar to: Predicción de valor máximo en superficie de respuesta, con paquete rsm

Hola compañeros de la lista. Los molesto con la siguiente duda. En un diseño central compuesto (CCD) con dos factores (V1 y V2) y una variable de respuesta (R), utilizando valores codificados (-1.4142, -1, 0, 1, 1.4182), al aplicar la orden: rsm.segundo.orden <- rsm(R ~ Bloque + SO(V1, V2), data = DATOS.Codificados) Obtengo el siguiente modelo: R = 103.92 -2.16

estimados, ajusté una superficie de respuesta con el paquete "rsm" de R y hago un grafico 2D de la superficie de respuesta con contour(), pero como el argumento de esta función es la superficie de respuesta ajustada y ésta se ha ajustado codificando las variables, de acuerdo a la recomendación de la documentación del paquete rsm, obtengo un gráfico con los ejes en unidades codificadas

Hi, I'm extracting data from a database with values for different observation types in the same variable (another variable deifnes the observation type). Some of these observation types are factors, so R naturally classifies the entire variable as a factor. I want to select a subset and convert the values to numeric values, but it isn't working; as shown below: >

Hello,everybody! I am a beginner of R. And I want to ask a question. If anybody would help me, thank you very much ahead. I want to plot something like a response surface, and I find the "rsm" package. Some commands are like this: #code head library(rsm) CR = coded.data(ChemReact, x1 ~ Time, x2 ~ Temp) CR.rsm = rsm(Yield ~ SO(x1,x2), data = CR) summary(CR.rsm) contour(CR.rsm,x1~x2)

Hi all (and especially Frank), I'm trying to use x=T, y=T in order to run a validated stepwise cox regression in rsm, having multiply imputed using mice. I'm coding model.max<-fit.mult.impute(baseform,cph,miced2,dated.sexrisk2,x=T,y=T) baseform is baseform<-Surv(si.age,si=="Yes")~ peer.press + copy.press + excited + worried + intimate.friend + am.pill.times +

Hola compañeros de la lista. Qué tal. Tengo un análisis de componentes principales, en el que se evalúan aproximadamente 1000 variables. Usando la función dudi.pca e inertia.dudi obtengo una cantidad de información sobre la influencia de las variables sobre los dos componentes principales. Me gustaría saber si existe alguna función que sobre esta información me arrojara la lista de

Hola compañeros de la lista. Tengo el análisis que muestro abajo, para la estimación de la Dosis Letal Media (DL50) por medio de regresión logística, de dos compuestos similares (denominados 1 y 2) aplicados a grupos de individuos similares, evaluando el número de individuos vivos y muertos al final del ensayo. Mi duda es qué forma me recomiendan para determinar si la diferencia es

Hola! No he podido consultar la doc. del paquete ade4, algo debe estar caído en CRAN ahora mismo. Dos cosas sobre la metodología -aun desconociendo los detalles de cómo lo hace ade4: El output de un PCA, los "pesos" de cada variable en las dimensiones de los componentes se interpretan como correlaciones, a mayor valor absoluto mayor asociación variable-componente. Ahora, como tales

Hola compañeros de la lista. Tengo el siguiente set de datos: Repeticiones <- c(rep("RI", 14), rep("RII", 14), rep("RIII", 14)) Tiempo <- rep(c(0, 2, 4, 6, 8, 10, 12, 24, 36, 48, 60, 72, 96, 120), 3) Concentracion_celular <- c(0.4862, 0.5375, 0.4309, 0.4390, 0.4603, 0.4733, 0.3936, 0.9085, 0.5838, 0.5477, 0.6331, 0.8693, 1.0092, 0.6341, 0.5350,

Hola compañeros de la lista, qué tal. Los molesto con la siguiente duda: Tengo un experimento con dos factores A y B, cada uno de los cuales tiene los siguientes niveles (que son concentraciones de dos hormonas vegetales aplicadas a plantas): niveles del factor A: 0, 0.2, 0.5, 1 niveles del factor B: 0, 0.1, 0.2, 0.5, 1 y mi variable de respuesta es continua, todo dentro del set de datos

Dear r users, I wanted to perform contour figure from response surface model result. I typed this: > model = rsm (Index ~ SO(NV, SKLON, pH), bonita) > summary(model) > par(mfrow = c(2, 3)) > contour (model, ~NV+SKLON+pH) However, I got the error answer as follows: Error in lmobj$data[, nm] : object of type 'environment' is not subsettable Has someone any suggestions to

Hello R experts I am looking for: - advice - sample commands - pointers in MASS 4E - packages That help to produce 1D and 2D response plots from quadratic RSM linear regression models that have been produced in R. Let me explain a little what I mean. For 1D plots I mean the variable range (either scaled or actual) on the X axis and the Y axis showing the model prediction (preferably with

Sorry everybody, temporary dyslexia. Sent from my BlackBerry wireless smartphone

Hola compañeros de la lista, qué tal. Estoy haciendo un análisis de componentes principales utilizando las funciones "dudi.pca" (paquete "ade4") y "PCA" (paquete "FactoMineR"). Sucede que al comparar las coordenadas de cada individuo que obtiene cada función, las que corresponden al segundo componente principal tienen idéntica magnitud pero con

Hi, I''ve been trying to get JRuby 1.5.3 with Rails 3 to run on the Tomcat6 server with little success. Has anyone been able to do this? If so, what issues did you have to overcome to get this to work? Also, is this a combination that you would recommend for a production site, or is it all too new and untested? The latest issue I''m stuck on right now is with the mysql-connector-

Dear all: I have a problem with calling R from Java, It was ok at the first time,but the error message "An unexpected exception has been detected in native code outside the VM. " will appear. What is the issue of "native code"? Could somebody help me ? Thanks, ken This is the log I obtained: executing: source('/export/home/users/ruser/java/Rmain.R') Loading

Hi. I rewrote the patch according to the comments. I adopted generating in-place code because it looks the quickest way. The point Eddie wanted to discuss is how to generate code and its ABI. i.e. in-place generating v.s. direct jump v.s. indirect function call Indirect function call doesn't make sense because ivt.S is compiled multi times. And it is up to pv instances to choose in-place

Have asterisk@home 1.2.1 The server is on an internal network eg 10.10.10.10 It is NAT'd 1:1 via Checkpoint firewall to external public IP eg 50.50.50.50 The remote IAX2 phone (ATCOM320) is configured to call 50.50.50.50 on extension 1055. Outbound calls to 1055 work perfectly. Inbound calls from 1055 get picked up as if it were an external call (see below) and goes straight to the ring
