Pspline smoothing
Dear all,
I'm trying to use the Pspline add-on package to fit a quintic spline
(norder =3), but I keep running into a Singularity error.

Error in smooth.Pspline(time, x, norder = 3) :
Singularity error in solving equations

only a problem with my installation. Things work fine in Linux but
not in Mac OS X (Darwin). Both system run the latest public versions
of R and Pspline.
predict.smooth.Pspline produces only NaN instead of predicted values
when norder>2:

Questions about piecewise spline fitting
Hi All,
I want to fit a piecewise spline of degree 1, i.e. a spline consisting of a
straight line over each piece. I downloaded the R package pspline, then I
have following questions:
1. in the program, the degree of the spline is specified by 2*norder-1. Why
do they adopt such scheme that we can only fit a spline with odd degree?
2. norder cannot be set to 1. Is there any specific reason for doing so?
Maybe I need to code this by myself. So I'd like to hear your advices.
Thanks in advance,
Gang

spline.des
Hello, I am using library fda and I can not run a lot of functions because
I receive the error:
Error in bsplineS(evalarg, breaks, norder, nderiv) :
couldn't find function "spline.des"
do you know how I can fix that? Thnaks. Liliana

Fitting spline using Pspline
...e n=4476, but not for
anything larger (say, n=4477). For example:
THIS WORKS:
-----------------------------
random = array(0,c(4476,2))
random[,1] = runif(4476,0,1)
random[,2] = runif(4476,0,1)
random = random[order(random[,1]),]
plot(random[,1],random[,2])
fit2 = sm.spline(random[,1],random[,2], norder=2, cv=FALSE)

THIS FAILS:
-----------------------------
random = array(0,c(4477,2))
random[,1] = runif(4477,0,1)
random[,2] = runif(4477,0,1)

predict.smooth.Pspline function not found

Beginner question
I'm a Beginner on R-language and I' have tried to use some packages but
the following message have appeared:
"Error in .Fortran("pspline", as.integer(n), as.integer(nvar),
as.integer(norder), :

I'm using a Windows version and I'd like to know if it is a installation
problem or problems with paths?
Thanks,
Marlon!!!

How to use the whole dataset (including between events) in Cox model (time-varying covariates) ?

the following code could be use to estimate (and plot) a smooth baseline
hazard:
> t<-seq(min(data$start),max(data$stop),length=100)
> lines(t,
predict(sm.spline(x=basehaz(coxfit)[,2],y=basehaz(coxfit)[,1],norder=2),

#there is a problem with this code. One should add the contraint that the
baseline hazard cannot be negative.
The following computes the parametric part of the cox model.
> risk <- predict(coxfit, type='risk') # gives exp(X'b)

Functional Data Analysis, fda_1.2.4
...ave more useful defaults and they return an object of class
'fdSmooth', with methods for 'plot', 'lines', and 'plotfit'. In
addition, there have also been improvements to the 'plotfit' function
and the 'CanadianWeather' data. Also, a function 'norder' has been
added, which returns the order of a B-spline.

Smooth monotone estimation on R
...oth monotone function to our data which correspond to a non-linear function.
We follow the example posted on the web, but in our case it did not apply.
We always get a straight line in response.
Which parameters we should change.
ind.basis = create.bspline.basis(c(min(time),max(time)),nbasis=38,norder=4)
Wfdob = data2fd(rep(0,length(time)),time,ind.basis)
fd = data2fd(alphaest,time,ind.basis)

Natural cubic splines produced by smooth.Pspline and predict function in the package "pspline"
Hello,
I am using R and the smooth.Pspline function in the pspline package to
smooth some data by using natural cubic splines. After fitting a
sufficiently smooth spline using the following call:
(ps=smooth.Pspline(x,y,norder=2,spar=0.8,method=1)
[the values of x are age in years from 1 to 100]
I tried to check that R in fact had fitted a natural cubic spline by
checking that the resulting spline was LINEAR outside the knots. I did this
by plotting the predicted values from the spline fitting in the following
way:

Splitting the large libguestfs repo
I got a little way into this. The two attached patches are
preliminary work.
My proposed split is:
libguestfs.git
common -> git submodule libguestfs-common.git
generator/
lib/
all language bindings
C based tools (eg. virt-df, virt-edit, guestfish)
guestfs-tools.git
common -> git submodule libguestfs-common.git
