similar to: lmomRFA-package: regsimq()

Dear List I?m using the ?lmomRFA? package to fit different distributions to my data sample. To calculate the error bounds I used: regsimq(?) and sitequantbounds(?) So my questions are: Are error bounds and confidence intervals the same thing? And: Does regsimq(? boundprob = c(0.05, 0.95)) calculate the 90 or the 95% confidence interval? If error bounds and confidence intervals are

Hello, I am using the lmomco package (lmom.ub and pargev) to compute the GEV parameters (location, scale, and shape), which are used to estimate return values. I was wondering how/if I can calculate upper and lower confidence (CI_u, CI_l) intervals for each return frequency using the GEV parameters to fill-in the table below? Xi (location) = 35.396 Alpha (scale) = 1.726 Kappa (shape) =

Dear List, I have a data frame with approximately 500000 rows that looks like this: ?Date??? time??? value ? 19.07.1956????????? 12:00:00?????????????? 4.84 19.07.1956????????? 13:00:00?????????????? 4.85 19.07.1956????????? 14:00:00?????????????? 4.89 19.07.1956????????? 15:00:00?????????????? 4.94 19.07.1956????????? 16:00:00?????????????? 4.99 19.07.1956????????? 17:00:00?????????????? 5.01

Hi all, I wrote a function that actually does what I want it to do, but it tends to be very slow for large amount of data. On my computer it takes 5.37 seconds for 16000 data points and 21.95 seconds for 32000 data points. As my real data consists of 18000000 data points it would take ages to use the function as it is now. Could someone help me to speed up the calculation? Thank you, Tonja

Dear List I hope you can help me: I?ve got a dataframe (df) within which I am looking for Peak Over Threshold values as well as the length of the events. An event starts when walevel equals 5.8 and it should end when walevel equals the lower threshold value (5.35). I tried ?clusters (?)? from ?evd package?, and varied r (see example) but it did not work for all events (again

respectd sir,  i am working on regional frequency analysis of flood flow data and want to use packages lmomRFA, lmom, imomco,etc andby using these i want to find RMSE , errorbounds and absolute biase but could not make it clear to use, please help regards atta muhammad asif assistant professor atta_ycc@yahoo.com [[alternative HTML version deleted]]

Hi all, I used contour() to add contour lines to a plot. Now I?m wondering if there is a way to get an output of the calculated x- and y- coordinates of the contour lines? Tonja

Hi all! I'm sure this is a stupid question but I can't find an answer. How can I fit the Gumbel distribution to my data using The Method of Moments in R? Thank you for helping me, Tonja

Dear all, I have a question concerning the ks.test() function. I tryed to calculate the example given on the German wikipedia page. xi <- c(9.41,9.92,11.55,11.6,11.73,12,12.06,13.3) I get the right results when I calculate: ks.test(xi,pnorm,11,1) Now the question: shouldn't I obtain the same or a very similar result if I commpare the sample and a calculated sample from the distribution?

In the first example you are performing a one-sample test against a continuous cumulative distribution (in this case a normal distribution). In the second case you are performing a two-sample test. You drew your values for x non-randomly by specifying fixed intervals along a normal distribution, but ks.test() just sees that you have provided two samples, not one sample and values along a

Dear R-helpers ? I have 7 data points that I want to fit a continuous curve to, that should look similar to a sine wave My data points would mark the local minima and maxima respectively. This is what I?ve got so far. And I would keep doing so, but sadly nls() then says that it has reached the maximum number of Iterations? ?

Hi List, Can someone help me to calculate the coordinates of the red and green points? In this example I found their approximate location by trying, but as I have to analyse many similar curves, I?d rather calculate the exact location. data<- c(0.008248005, 0.061242387, 0.099095516, 0.189943027, 0.227796157, 0.258078661, 0.280790538, 0.303502416, 0.386779301, 0.454914934, 0.545762445,

I would like to change the position of the major tick marks in my qq-plot? Right now the ticks are set at 5.5, 6.0, 6.5 and 7.0. I would like them to be at 5.4, 5.6, 5.8, 6.0, 6.2, 6.4, 6.8 and 7.0. So I would have to remove some of the present ticks. So far I can only add ticks to the plot with: axis(1,at=c(5.4, 5.6, 5.8, 6.0, 6.2, 6.4, 6.8, 7.0)) Is there a solution to my

Hi.....I am relatively new to R but was quite pleased with myself at having generated a series of lattice plots as PDFs. I was very surprised when plotting these out as jpegs (or png or tiff) that the strip title information above each lattice plot vanished. The pdf was fine. Has anybody any ideas? I can't add an image as the information is sensitive. Many Thanks Steve Creamer Here is the

On a Windows platform I am trying to count the number of lines in a file. In a DOS window, the following works: C:\Users\jar>findstr /R /N "^" D:\my_dir\my_file | find /C ":" 5317 (it works with double \\ also) But in R, I need to make this string up with the file name I get from file.choose(): filename = file.choose() #get the number of lines in the file # first make a

Dear R-help community, My main goal of this message is to find a way of skipping a file of a month/year in a loop that does not exist (and making it's output into an data.out array would be NA) and moving onto the next year/month in the loop to carry on filling data.out with real precipitation data. The situation so far: I downloaded 50 years worth of GRIB data files from the NCEP data

Hi Jenny If you want a general solution I understand. However I just downloaded the file fine (as far as I can tell) so you are welcome to have a copy. I can email it to you if you want. I do not think your test for NA is valid. i.e if(test != "NA"){ } I think you should use if(is.na(test)){ } Or something similar. J --- John Seers Institute of Food Research Norwich
