Generate simulated data respecting some conditions
Hello, Is it possible to generate simulated data that look like the attached figure? The curve in the figure can be obtained from this equation respecting some conditions: if(Temperature > T_min & Temperature < T_max){ a*( Temperature -T_min)*( Temperature -T_max) } else 0 T_min ~ Uniform(0, 24) T_max ~ Uniform(25, 45) -a ~ Gamma(1, 1) Temperature <- seq(0, 45, by = 1)

Best method to add unit information to dataframe ?
Dear all, I'd like to have a dataframe store information about the units of the data it contains. You'll find below a minimal exemple of the way I do, so far. I add a "units" attribute to the dataframe. But I dont' like the long syntax needed to access to the unit of a given variable (namely, something like : var_unit <- attr(my_frame,

survival::predict.coxph
Hi, if I got it right then the survival-time we expect for a subject is the integral over the specific survival-function of the subject from 0 to t_max. If I have a trained cox-model and want to make a prediction of the survival-time for a new subject I could use survfit(coxmodel, newdata=newSubject) to estimate a new survival-function which I have to integrate thereafter. Actually I thought

spec.pgram returns different spectra when fast=TRUE and the number of samples is odd
Dear all, This is potentially a bug in spec.pgram, when the number of samples is odd,spec.pgramreturns a different result withfast = TRUE, the example below contains the two varieties with a reference spectrum calculated manually. the number of returned spectra is also larger (50 compared to 49) whenfast = TRUE x <- rnorm( 99 ) plot(spec.pgram(x, taper = 0 , detrend = FALSE , plot =

gc relocations on exception path w/RS4GC currently broken
Sorry to reply to myself here, but I had an idea regarding "issue #2" -- possibly what makes the most sense for those clients/targets is to pull the pointer difference computation/reapplication into RS4GC itself -- it could have a pass just before or after rematerialization, which runs based on a configuration flag (eventually to be driven by GCStrategy), which performs rewrites like

[PATCH 0 of 2] libxl: add libxl_domain_config_init
The following series implements libxl_domain_config_init as per the libxl API requirement that each type has an init function. The first function does this in an open coded manner and is proposed for Xen 4.2. The second function is RFC only since it moves the definition of this type into the IDL and makes the required infrastructure updates to enable this. I think this is more 4.3 material at

A mistake in garchFit()? {fGarch}
Hello, I was using garchFit {fGarch} to fit some GARCH processes. I noticed that the result contains "Log Likelihood" value (right above "Description"), but when I use .. at fit$llh to retrieve Log Likelihood value, the sign switched. I am confused about which value I should choose to report... Any help here? Thanks a lot! Ted -- View this message in context:

gc relocations on exception path w/RS4GC currently broken
Thanks, I think that's a useful way to look at it (though if I wanted to bikeshed I'd suggest the name "DoubleIndirect" as a bit more precise than "VeryIndirect"). An aspect of it that I'm still puzzling over is that my target runtime (at least in its current form) doesn't have a way to represent/process a "VeryIndirect" pointer. So I'd like to

FYI: gc relocations on exception path w/RS4GC currently broken
For anyone following along on ToT using the gc.statepoint mechanism, you should know that ToT is currently not able to express arbitrary exceptional control flow and relocations along exceptional edges. This is a direct result of moving the gc.statepoint representation to using a token type landingpad. Essentially, we have a design inconsistency where we expect to be able to

RFC: Adding 'no-overflow' keyword to 'sdiv'\'udiv' instructions
Introduction: We would like to add new keyword to 'sdiv'\'udiv' instructions i.e. 'no-overflow'. This is the updated solution devised in the discussion: http://lists.llvm.org/pipermail/llvm-dev/2017-October/118257.html The proposed keywords: "nof" stands for 'no-overflow' Syntax: <result> = sdiv nof <ty> <op1>,

[PATCH 00/28] libxl: ocaml: improve the bindings
The following series of patches fill in most of the gaps in the OCaml bindings to libxl, to make them useful for clients such as xapi/xenopsd (from XCP). There are a number of bugfixes to the existing bindings as well. I have an experimental version of xenopsd that successfully uses the new bindings. An earlier version of the first half of the series was submitted to the last by Ian Campbell on

creating a vector of sums
Hi, I am trying to create a function for a goodness-of-fit test for the Pareto Distribution for some loss data that I have. So far I have the following: function(X=OTOL) { n <- length(X)-1 #calculated the number of values (extra as 0 included) i <- 2:640 #values of i j <- 1:639 #values of i-1 Y <- (n-j+1)*((X[i])-(X[j])) #First part of GoF model Y } Where OTOL is the ordered loss
