Hello, How can I run a backward stepwise regression with part of the variables fixed, while the others participate in the backward stepwise analysis?

Hello, I'm trying to fminimize the following problem: You have a data frame with 2 columns. data.input= data.frame(state1 = (1:500), state2 = (201:700) ) with data that partially overlap in terms of values. I want to minimize the assessment error of each state by using this function: err.th.scalar <- function(threshold, data){ state1 <- data$state1 state2 <- data$state2

Hi, I want to remove the entire row from the dataset if any of the row contains blank or NA my dataset look like State Year Y X2 X3 X4 X5 X6 State1 1960 27.8 397.5 42.2 50.7 78.3 65.8 State2 1960 29.9 413.3 38.1 52 79.2 66.9 State1 1961 29.8 439.2 40.3 54 79.2 67.8 State2 1961 30.8 459.7 39.5 79.2 69.6 State1 1962 31.2 492.9 37.3 54.7 77.4 68.7 State2 1962 528.6 38.1 80.2 73.6 State1 1963

Hi I have records like like this X1 X2 State 34 72 state1 9 63 state1 49 31 state1 60 34 state1 80 73 state1 60 20 state2 59 87 state2 88 20 state2 71 66 state2 65 56 state2 59 16 state1 60 100 state2 I want to get the summarize value like mean median histogram for X1 and X2 based on state. I'm using FOR loop for this. Is there any method to remove for loop and use apply or any

Hi I'm using fracdiff package to estimate the parameters of a fractionally-differenced ARIMA (p,d,q) model, and it works fine, but I wanted to have also the filtered series and the series of residuals. I understand these are calculated in the subroutine fdfilt, in the program fdcore.f, but I can't manage to get them out. Any suggestion would be much appreciated Thanks Susana Barbosa

Deare R users I am new to R. What I want to do is explained below;- I have table called States.Prob which is given below:- This table gives the probabilities of the changes in the swap curve depending on the state of the swap curve. I want to put these probabilities in my dataframe mydata(given after the prob table). Prob of States Changes State1 State2 State3 State4 a

I'm trying to write a function that takes several objects with many different attributes and then changes their attributes. So what I wanted to happen in the simplified example below is for the function to change the attributes of the objects state1 and state2 that are passed to it. But because stateA and stateB are local, this isn't working. Are there any easy solutions? e.g., if I could

Hello everybody! I'm quite new using R and i'm trying to develope a function, but i have a problem. What i want to build is something like an objects vector. I have a list with two tables, and after or next to them, I want to add more tables or vectors to that list one by one. But i cannot find how to do it! Does someone can help me? I will be very grateful for any of your help!

Dear all, I cannot find to explicitly get the R-squared or adjusted R-squared from summary(lm()) Thanks a lot! [[alternative HTML version deleted]]

Hi All, We are currently in the process of testing Solaris 10 with ZFS and Oracle and are running it on a T2000. When checking performance statistics on the T2000, we notice that only one thread of the CPU appears to be doing any of the processing. Leaving all other threads seemingly idle. Are there any tuning parameters that need to be set or changed when running Oracle on T2000 using

Does anyone know about this device? SESX3Y11Z 32 GB 2.5-Inch SATA Solid State Drive with Marlin Bracket for Sun SPARC Enterprise T5120, T5220, T5140 and T5240 Servers, RoHS-6 Compliant This is from Sun''s catalog for the T5120 server. Would this work well as a separate ZIL device for ZFS? Is there any way I could use this in a T2000 server? The brackets appear to be

Muy buenas, quiero calcular correlaciones de Pearson entre dos variables (a,b) teniendo en cuenta una tercera (c). Para ello estoy usando una función llamada "pcor.test" (http://www.yilab.gatech.edu/pcor.html), que en realidad no está en ningún paquete de R, que yo sepa. ¿Alguien conoce una función similar en alguna librería de R? Por otro lado, para ver si me cuadraban los resultados,
