Help with NaN when 0 divided by 0
...n my case I never get Inf, just NaN because of the structure of my dataset. Here’s a dumb example: var1 <- c(0, 500, 5379, 0, 1500, 1750) var2 <- c(0, 36, 100, 0, 10, 5) var1/var2 I realize the NaNs are logical, but for my purposes this should just be 0 because I am calculating expenditures and if you spent no money in one sub-area and none in the whole area then you don't have an expenditure at all, so it should be 0. And since R doesn't like adding NA's or NaN's to anything, I'd rather just have this be 0 so that my future calculations, such as adding up expend...

Fwd: Documenting data sets with many variables
...es Date: Friday 05 August 2005 14:03 From: Arne Henningsen <ahenningsen at email.uni-kiel.de> To: R-help at stat.math.ethz.ch Hi, I extended the data set "Blanciforti86" that is included in my R package "micEcon". For instance, I added consumer prices, annual consumption expenditures and expenditure shares of eleven aggregate commodity groups. The corresponding variables in the data frame are called "pAgg1", "pAgg2", ..., "pAgg11", "xAgg1", "xAgg2", ..., "xAgg11", "wAgg1", "wAgg2", ..., "wAgg1...

Double hurdle model in R
...can write the model in the following way: if (z'a + u > 0 & x'b + e > 0) y = x'b + e, else y = 0 In the model, consumption y is the (left-) censored dependent variable. e and u are the normally distributed error terms. z'a is the participation equation and x'b is the expenditure equation. If we would remove the participation equation from the model we would end up with a type I tobit-model. In the tobit-model the same set of paprameters and variables determine both the discrete probability of non-zero outcome and the level of positive expenditure. In the double-hurdle-mod...

weighted mean
How do I go about generating a WEIGHTED mean (and standard error) of a variable (e.g., expenditures) for each level of a categorical variable (e.g., geographic region)? I'm looking for something comparable to PROC MEANS in SAS with both a class and weight statement. Thanks. Marc [[alternative HTML version deleted]]

Q:Truncated Regression Model
Hi, Problem: I have the ususal linear regression model y=Xb but I cant observe y (expenditure for a particular good) for some y <c where c is fixed for all observations. But I can observe the corresponding covariates x (incom). I used the survivla5 library (survreg(Surv(y,y<c,type="left")~x) for a censored regression model (thanks again for this tip). Is there a way to est...

Complex Surveys...Specifying Design
I need some guidance from someone who is familiar/has some experience with the survey package. The data that I am using is from the Medical Expenditure Panel Survey (www.meps.ahrq.gov <http://www.meps.ahrq.gov/> ). The STRATA and PSU variables are varstr01 and varpsu01 respectively. When I try to specify them with the svydesign function I get an error message. An excerpt of my session is as follows... library(foreign) > h60 <-...

Standard error of coefficient in linear regression
...talk about in the linear regression and I'm really confused. The question is: How exactly are standard errors of coefficients calculated in the linear regression? Here's an example from a website I've read [1]. A company wants to know if there is a relationship between its advertising expenditures and its sales volume. ======================================================== > exped <- c(4.2, 6.1, 3.9, 5.7, 7.3, 5.9) > sales <- c(27.1, 30.4, 25.0, 29.7, 40.1, 28.8) > S <- data.frame(exped, sales) > summary(lm(sales ~ exped, data = S)) Call: lm(formula = sales ~ exped...

Fax and PRI
I'm setting up a small office PBX on asterisk, and I've got to the point where I have to decide on what to do about FAX. The current situation is: PRI (E1) connected to an E100 and sip hard phones on their own network. I'd like to add some very limited fax capability to the system. Basically we need to send a couple of faxes a month, and receive about the same number. My options

Tobit model on unbalanced panel
Appreciate any suggestions regarding how to fit an unbalanced panel data to a Tobit model using R functions. I am trying to analyze how real estate capital expenditures (CapEx) are affected by market conditions using a panel Tobit model. The CapEx is either positive or 0, so it is censored. The data are unbalanced panel, including the CapEx of about 5000 properties over about 40 quarters, with the starting and ending quarters differ across properties. In case yo...

F distribution from lme()?
Dear all, Using the data set and code below, I am interested in modelling how egg temperature (egg.temp) is related to energy expenditure (kjday) and clutch size (treat) in incubating birds using the lme-function. I wish to generate the F-distribution for my model, and have tried to do so using the anova()-function. However, in the resulting anova-table, the parameter kjday has gone from being highly non-signiicant in the lme-express...
