How to create design matrix for LLMNL?
Hello,
I have a small problem with developing design matrix X, which I use in
estimation the log-likelihood of a multinomial logit model.
I have the data:
number of observation - 289
number of choice alternative- 3
number of choice specific variables in matrix X -4
matrix X =289x4
I tried to use the function createX, I know that I have to get design matrix
289x12 (am I right?) but

loop to subtract arrays / error
Hi everyone, I am having trouble with creating a loop to subtract arrays.
In R, this is what I have done:
> Vobsr <- read.csv("Observed_Flow.csv", header = TRUE, sep =",") # see data
> below
> Vsimr <- read.csv("1000Samples_Vsim.csv", header = TRUE, sep =",") # see
> data below
> Vobsr <- as.matrix(Vobsr[,-1]) # remove column 1 from

subtract multiple columns from single column for Nash Sutcliffe efficiency
Hi everyone, I am having trouble using my own data in the Nash-Sutcliffe
efficiency (NSE) function.
In R, this is what I have done:
Vobsr <- read.csv("Observed_Flow.csv", header = TRUE, sep =",") # see data
below
Vsimr <- read.csv("1000Samples_Vsim.csv", header = TRUE, sep =",") # see
data below
Vobsr <- as.matrix(Vobsr[,-1]) # remove column 1

[PATCH net-next RFC 0/3] virtio-net: Conditionally enable tx interrupt
Hello all:
We free old transmitted packets in ndo_start_xmit() currently, so any
packet must be orphaned also there. This was used to reduce the overhead of
tx interrupt to achieve better performance. But this may not work for some
protocols such as TCP stream. TCP depends on the value of sk_wmem_alloc to
implement various optimization for small packets stream such as TCP small
queue and auto

virtio-scsi <-> vhost multi lun/adapter performance results with 3.6-rc0
Hi folks,
The following are initial virtio-scsi + target vhost benchmark results
using multiple target LUNs per vhost and multiple virtio PCI adapters to
scale the total number of virtio-scsi LUNs into a single KVM guest.
The test setup is currently using 4x SCSI LUNs per vhost WWPN, with 8x
virtio PCI adapters for a total of 32x 500MB ramdisk LUNs into a single
guest, along with each backend
