A young colleague (Matthew Keller) who is an ardent fan of R is teaching me much about R and discussions surrounding its use. He recently showed me some of the sometimes heated discussions about Type I and Type III errors that have taken place over the years on this listserve. I'm presumptive enough to believe I might add a little clarity. I write this from the perspective of someone old

Folks, Normally, in a data frame, one observation counts as one observation of the distribution. Thus one can easily produce a CDF and (in Splus atleast) use cdf.compare to compare the CDF (BTW: what is the R equivalent of the SPlus cdf.compare() function, if any?) However, if each point should not count equally, how can I weight the points before comparing the distributions? I was thinking of

Hi, For the package "pls", I need to understand the algorithm for "simpls.fit" for Partial Least Squares. I'm not sure if simpls.fit tries to find the weight vectors (loadings) to maximize which of the two: Cov(Xw, y) or maximize Cov^2(Xw,y)? Are these objective functions equivalent? (in some texts, they use the first and in other texts, they use the second obj.

Hi Duncan I tried Ecdf and/or wtd.quantile from Hmisc and it is working (probably).

Hi Petr, I think that Duncan suggests something like this: x<- c(rep(10,20), rep(300,5), rep(100, 10)) tx <- table(x) prop.x <- tx / sum(tx) vx <- as.integer(names(tx)) prop.wx <- tx * vx / sum(tx * vx) plot(ecdf(x)) plot(vx, cumsum(prop.x), ylim = 0:1) plot(vx, cumsum(prop.wx), ylim = 0:1) Best regards, Thierry ir.

Yeah, I have its datasheet (it's a Xantrex XW invertor by the way). I do not know why creating a more-or-less generic driver is an issue. Of course, there are Modbus beasts that can scare everyone but mostly one would need to read either intreger or float numbers out of Modbus registers in order to decide whether or not to start or stop the shutdown process. 24 ???? 2017 ?. 19:25:14
