Convert list of lists <--> data frame
For a function that takes an argument as a list of lists of parameters, I'd like to be able to convert that to a data.frame and vice versa, but can't quite figure out how. pats <- list(structure(list(shape = 0, shape.col = "black", shape.lty = 1, cell.fill = "white", back.fill = "white", label = 1, label.size = 1, ref.col = "gray80", ref.grid = "yes", scale.max = 100), .Names = c("shape", "shape.col", "shape.lty"...

Function not returning a vector?
Why does: (shape/scale) * (1:365/scale)^(shape - 1) return a vector of numbers but calling a function hasard(1:365,shape,scale) defined like: hazard <- function(x,shape,scale) { return (shape/scale) * (x/scale)^(shape - 1) } Only return a single value? It is like x becomes a single value passed as an arg...

Fitting Beta Distribution
I answer my own question: I had overlooked the fact that the normalization factor is also a function of the parameters I want to optimise, hence I should write dbeta2 <- function(x, shape){ res <- x^(shape-1)*(1-x)^(shape-1)/beta(shape, shape) return(res) } after which the results are consistent. ---------- Forwarded message ---------- From: Lorenzo Isella <lorenzo.isella at yopmail.com> Date: 21 December 2017 at 11:29 Subject: Fitting Beta Distribution To: &q...

fGarch: garchFit and include.shape/shape parameters
Hello, The function garchFit in the package fGarch allows for choosing a conditional distribution, one of which is the t-distribution. The function allows specification of the shape parameter of the distribution (equal to the degrees of freedom for the t-distribution), for which the default is set to 4. The function also includes an option "include.shape", which is "a logical flag which determines if the parameter for the shape of the conditional distribution wi...

lc shaping in- and outbound traffic on same box
I''m looking for a way to shape all traffic on a virtual vlan interface, say eth1.100 to a max of 100mbit. The box is a quagga router with eth0 on the inside and vlan interfaces on the eth1 card to our upstream partners. Each partner has his own vlan on eth1. I tried shaping but was only able to shape outbound traffic on the...

MASS fitdistr with plyr or data.table?
I am trying to extract the shape and scale parameters of a wind speed distribution for different sites. I can do this in a clunky way, but I was hoping to find a way using data.table or plyr. However, when I try I am met with the following: set.seed(144) weib.dist<-rweibull(10000,shape=3,scale=8) weib.test<-data.table(cbi...

Fitting Beta Distribution
Dear All, I need to fit a custom probability density (based on the symmetric beta distribution B(shape, shape), where the two parameters shape1 and shape2 are identical) to my data. The trouble is that I experience some problems also when dealing with the plain vanilla symmetric beta distribution. Please consider the code at the end of the email. In the code, dbeta1 is the density of the beta distri...

vlan traffic shaping.
I couldn''t find anyone who had actually made it work via google so I guess I''ll ask here. My setup is a VPN point to point link. The VPN is a modified version of Openvpn where I''m using zlib compression to improve the compression a bit. The goal is to shape traffic coming from a routing server through the vpn to the endpoint of the vpn and in such a way maximize the usefulness of a limited bandwidth connection. You can shape the vpn tunnel just fine, but that has a problem since you shape the traffic _before_ any of it is compressed and thus cannot r...

CLIENT <--- eth0 ----> SQUID <----- ppp0 -----> NET What I just realised was that all egress traffic on eth0 gets shaped, squid gets data from ppp0 and hence is not shaped. Does this mean that...
