Homework help: Is this how CI using t dist are constructed?
I'm trying to replicate some of the examples from my textbook in R (my text uses Minitab). In this problem, I'm trying to construct a 95% confidence interval for these distance measurements [1]: > # Case Study 7.4.1, p. 483 > x <- scan() 1: 62 52 68 23 34 45 27 42 83 56 40 12: Read 11 items > alpha<-.95 > mean(x) + qt(c((1-alpha)/2, 1-((1-alpha)/2)), df=length(x)-1) *

Homework help: t test hypothesis testing with summarized data?
Is this how a t hypothesis test is done when I don't have the actual data, but just the summarized statistics: > #Homework 9.2.6 [1] > n<-31 > xbar<-3.10 > s_x<-1.469 > m<-57 > ybar<-2.43 > s_y<-1.35 > s_pooled<- (((n-1)*s_x^2) + ((m-1)*s_y^2)) / (n + m - 2) > s_pooled [1] 1.939521 > t_obs <- (xbar - ybar) / (s_pooled * (sqrt(1/n + 1/m)))

Caller ID with DTMF
Hi Everyone! I live in Sweden and can not get CallerID to work on analog incoming lines. I m trying to find out if DTMF style CallerID works on a FXO card (X100). I`v seen one solution with a modem attached in parallel with the X100 just to provide the ID on its serial port. It must be much better if this can be implemented in to the X100 driver. Any info about this would be highly appreciated.

quite complicated case(the repeated data arranage~)
Hi everyone: I have been struggling with this repeated data type for whole afternoon,I sent two emails to server for help,many people kindly responded , hereby thank you so much,but since I dont want to write to much in email,so I divide the problem in parts,so far this seem did not work out very well,so this is my whole problem~ first I have example of data here:

Calculating confidence in an estimate including number of trials?
[Yes, this is related to a homework problem, but is not the problems itself.] In my mathematical statistics class, we've just learned about properties of estimators, and I can now solve manually problems like this: A sample of size n = 16 is drawn from a normal distribution where sigma = 10 but mu is unknown. If mu = 20, what is the probability that the estimator mu hat = Y bar will lie

simple question on glm
Hi, I am trying to use glm to fit my data, wondering if there is a easy way to fit a glm without typing all the explanatory variable names. For example, if I have 100 explanatory variables x1, x2, ..., x100 and response variable is y, I don't want to do something like glm1 <- glm(y ~ x1 + x2 + ... + x100, family = gaussian, data = dataA) since it would be a lot of typing. Many thanks,

IAX2 hard phone
I purchased an IAX2 hardphone, X100 otherwise known as a Netweb X100 or YWH100 with a PA168 chip and the latest firmware 1.45 available, from a US retailer. I was able to configure the phone to work with my Asterisk box, except the hold and transfer buttons do not work. When you press the hold button, it rings endlessly, the transfer button, displays "transferring" but it does nothing.

shading (fill) the area between two lines
Dear All: I am trying to shade the area between the two lines; *line 1* and *line 2*. You can use this code as an example. x100<-c(-1,1,2,3,4,5,6,3) y100<-c(4,5,3,1,4,4,2,-1) plot(x100,y100) *##### line1* abline(a=-(Beta0-1)/Beta[1,2], b=-Beta[1,1]/Beta[1,2], lwd = 3, col="skyblue", lty=3) ##### lty=3, *##### line 2* abline(a=-(Beta0+1)/Beta[1,2],

Module wcfxs - is it not part of astlinux?
Hello I am (attempting) to run the astlinux version of Asterisk on a VIA embedded platform. I have a TDM04B and pretty sure zaptel.conf and zapata.conf setup OK. They worked fine with same card in traditional PC anyway. I think need the module wcfxs for a Digium TDM04B card. Is this module not part of astlinux? Do I need to download it? Or is it in opt? I see wctdm - but think that is

model.frame problem
A few weeks ago I reported a problem with model.frame, whose root lay in a formula expression "....+ ratetable(x1=x1, x2=x2, ....x100=x100)" that was really long and caused model.frame to fail. Brian had some indefinite ideas on what might need to change in the base code to handle it. In survival_2.36-1 the bit of code that generated the offending expression has been changed (mostly

IP PHONE iareaphone x100, tested??
Hi, I have used the Budgetone 102's extensively on Asterisk and found then quite reliable as long as you update the firmware. The GXP2000 is quite a mess at the moment as the current firmware does not support 3 quarters of the advertised functions and codec support is extremely limited. I have tested the unreleased latest firmware update for the GXP2000 and it's an incredible difference

FAX connected to a TDM400 card port
Hi, I have a FAX machine connected to a TDM400 card FXS port. When I receive a fax call through X100 and transfer it to that extension, the FAX machine display REC, but nothing happen (no fax received). There is something special to be done for this configuration? Thanks, Dan
