About Mcneil Hanley test for a portion of AUC!
Dear all I am trying to compare the performances of several methods using the AUC0.1 and not the whole AUC. (meaning I wanted to compare to AUC's whose x axis only goes to 0.1 not 1) I came to know about the Mcneil Hanley test from Bernardo Rangel Tura and I referred to the original paper for the calculation of "r" which is an argument of the function cROC. I can only find the value of "r" for the whole AUC's . > seROC<-function(AUC,na,nn){ > a<-AUC > q1<-a/(2-a)...

factanal question
...(provided the factor model fits the data) this would be useful. Of course you would need to submit the data to the function to get the residuals (not just their correlation matrix), but it should be possible to get the residual correlation matrix if only the data correlation matrix is provided.

Source of chickwts data
...elp list.) My question is about the "chickwts" data in the datasets package. According to help(chickwts), the source of the data is ?Anonymous (1948) Biometrika, 35, 214. But this reference seems irrelevant. (See http://www.jstor.org/stable/i315414.) The help document also gives "McNeil, D. R. (1977) Interactive Data Analysis. New York: Wiley" as a reference, but unfortunately my local library does not keep the book. Could someone please help me find the correct source of the data? Many thanks. Chirok

controller filters running twice in 1.1.4?
since upgrading to 1.1.4 (I had been running without issue on a git snapshot), I''m noticing that my filter actions initiated from application.rb seem to be running twice. I created a test rails project with the rspec scaffold and am also seeing the same behavior here too. Adding this code to application.rb: before_filter :foo def foo "foo" end and an example

How to create a 'fit' plot
...et and want to fit, say, three distributions to it. I would like to create a plot that shows my data points against all three fitted curves (estimated d.f.). Basically, I lookint to creat a plot that looks like the one presented in the attached paper (Figure 5, page 12): http://www.math.ethz.ch/~mcneil/ftp/astin.pdf Could you please show me, or point me to example code showing, how that can be done? Thanks,

Standard error for the area under a smoothed ROC curve?
...hp "The 95% confidence interval for the area can be used to test the hypothesis that the theoretical area is 0.5. If the confidence interval does not include the 0.5 value, then there is evidence that the laboratory test does have an ability to distinguish between the two groups (Hanley & McNeil, 1982; Zweig & Campbell, 1993)." But aside from early on the above article is short on details. Can anyone tell me how to calculate the CI of the AUC calculation? I read this... http://www.bioconductor.org/repository/devel/vignette/ROCnotes.pdf Which talks about resampling (by showing...

This "figure" tries to capture what I am explaining theta1 theta2 x1 x2 x3 I try to follow McNeil (2006) http://www.ma.hw.ac.uk/~mcneil/ftp/NestedArchimedean.pdf with R as the programming language.

Competing Risks Analysis
...uot; is variable unique to each subject. (The method of fitting found in WLW, namely to do individual fits and then glue the results together, is not necessary). 2. If a given subject can have at most one event, then it is not clear that the sandwich estimate of variance is necessary. See Lunn and McNeil, Biometrics (year?) for an example. 3. The covariates can be coded any way you like. WLW put in all of the strata * covariate interactions for instance (the "x" coef is different for each event type), but I never seem to have a big enough sample to justify doing this. Lunn and McNeil use...

how to estimate dose from respond given drc package result
Dear all, I can use the very nice drc package (multdrc()) to model and plot a dataframe containing dose and response values. I can also use predict.drc() to yield response values given a dose. I need to do the opposite, estimate a dose given the response. The general predict documentation seems to say that this is possible, but it does not appear that predict.drc has that capability.

virsh confirmed edits do not persist
This may be user error, I am new to libvirt. I am using libvirt 5.0.0. I have created a VM (win10) in the system URI using virt-manager. I stopped the VM to edit it. I set my LIBVIRT_DEFAULT_URI="qemu:///system" and am able to read the domain configuration with `EDITOR=nano virsh edit win10`. When I save (ctrl+o) and exit (ctrl+x) I see the message "Domain win10 XML configuration
