Hi, I have a problem with a regression I try to run. I did an estimation of the market model with daily data. You can see to output below: /> summary(regression_resn) Time series regression with "ts" data: Start = -150, End = -26 Call: dynlm(formula = ror_resn ~ ror_spi_resn) Residuals: Min 1Q Median 3Q Max -0.0255690 -0.0030378 0.0002787

Hi, when I run a nmap localhost I see that port 199 is open for the smux service but when I check the services gui in runlevel 3 or 5 I don't find it.

Does anyone know how to colse this service? regards, ivago -------------- next

Hi all, I have a dataset with several variables, each of which is a separate column. For each variable, I want to produce a boxplot and include the name of the variable (ie, column name) on each plot. I have included a sample dataset below. Can someone tell me where I am going wrong? Thank you for your help, Shawn Morrison # Generate a sample dataset var1 = rnorm(1000) var2 = rnorm(1000)

Hello, for my diploma thesis I need to program a solver for Merton?s respectively Black?s and Scholes? Option pricing formula, which should be achieved for several dates. What I want to do is to estimate the value of a firm?s assets "vA" (x[2] denotes vA) and the option-implied volatility of firm?s assets "sigA" (x[1] denotes sigA) by solving it simultaneous using the Black

Hello all! I would like to create a 3d plot, with the option price explained by the underlying price and time. Unfortunately, I can't quite get it to work. I would very much appreciate your help! Thanks, Anna # Black-Scholes Option Graph library(lattice) blackscholes <- function(s, k, r=.1, t=5, sigma=.9,call=TRUE) { #calculate call/put option d1 <-

Hello, I'm trying to create a custom function that "mean-centers" data and can be applied across many columns. Here is an example dataset, which is similar to my dataset: *Location,TimePeriod,Units,AveragePrice* Los Angeles,5/1/11,61,5.42 Los Angeles,5/8/11,49,4.69 Los Angeles,5/15/11,40,5.05 New York,5/1/11,259,6.4 New York,5/8/11,187,5.3 New York,5/15/11,177,5.7

Hi, Is there a way in sieve to get the current date, preferably in YYYYMMDD format? To what I've found it's hard to achieve. I have tried including a :global sieve script in which I would set the current date to a certain variable and overwrite this included script every day. But to my disappointement variables set in an included script do not exist in the original script... In fact what

hey guys, I''ve been noticing that I get a LOT of rails digest emails each day - is it possible to restrict this to once a day (hence a digest) and have a single, larger email? there are usually only a handful of messages per digest. I''m not sure if this has been discussed before, but I didn''t see any way to control the fequency of digest mails at

Hello List I'm trying to calculate the median period (in months) of a set of time intervals (between two interventions). I have been playing with the lubridate package to create the intervals but I can't think of the right approach to get the median timeperiod. Toy code: library(lubridate) test <- c('08-04-22', '08-07-28', '09-03-02', '09-03-03',

Hi System: Dell PowerEdge Dual Processor O/S: Redhat 7.3 + most patches Kernel: RH compiled 2.4.18-19.7.xsmp Not sure whether this is an ext3 problem or not, but I've not seen this on other RH systems. There is a particular file on an ext3 filesystem that hangs whichever process tries to access it, i.e. an attempt to cp it will hang the cp. the process is unkillable, and a reboot is the

Hi there, can anyone tell me how to extract to values of a particular slot for some S4 object?

Dear ALL, I saw this in article from mongrel faq, Q: Mongrel stops working if it''s left alone for a long time. If you find that Mongrel stops working after a long idle time and you''re using MySQL then you''re hitting a bug in the MySQL driver that doesn''t properly timeout connections. What happens is the MySQL *server* side of the connection times out and

Hello, I have 2 servers which share 2 partitions with drbd, on each machine runs one VM on the drbd device, so that I have primary/secondary and secondary/primary drbd devices. There are also some more XEN VM?s that only do aa mysql replication and one is standalone. In the last 4 weeks I had 2 incidents where both machines did a sudden reboot, first one machine and 2 minutes later the other one.

Hi R-users: How can I format a daily time serie with ts function so the plot of the time shows the date right (dd/mm/yy) or yy.xxxx ?

Hi there, What is the best way to get a time series of daily stock price observations into R (from excel). The time series are daily but there are spaces for w/e's and holidays etc. So I am not sure a ts object will be suitable but I am not sure what I should use? What ever package you recemmned i need to be able to run a corrolelagram. Thanks Hugh -- View this message in context:
