Hello Achim Zeileis,
gt; We are trying to find out how to get the variance-covariance matrix of the
gt; MLEs out of the glm function. Can anyone help?
Please try this :
Suppose you have
summary(glm(A ~ B,data=abc, family=Gamma))
then use
summary(glm(A ~ B,data=abc,
Dear R users,
I am using a loop that does matrix multiplication in a manner
(A%*%B)%*%(A)
Here A is a row of data frame D of order(200x4). B is a (4x4). No need to say
D[j,] is 1x4
so I am using
for(j in seq(0.1,20,by=0.1)){
Slt;- (D[j,]%*%B)%*%(D[j,])
print(S)
}
As a
Dear All,
Can somebody tell me how to do Maximum Likelihood Estimation in R
for Non-linear function?
My function is non-linear and it has four parameters, only one explanatory
variable.
If possible Please tell me the source so that I can write my own code for above.
Thanks,
GS
Dear All,
I have a dataset containing Date column. I need to breakdown this dataset into
two parts one which has datapoints before a particular date and the otherone on
or after a particular date.
for example:
2005-12-15,
2008-12-14,
2012-10-01,
2009-11-15,
2018-10-10,

Dear All,
I have some problem in R which I'm explaining using an example:
x-(120,235,172,95,175,200,233,142)
i want to remove the elements which are lesser than 100 and as a result i want
two vectors
y-(containing elements 100)
z-(remaining elements)
Moreover if I wish to use two different
Dear All,
I am using R and I am putting my problem in form of an example:
X-c(128,34,153,987,345,45,3454,23,123)
I want to remove the entries which are lesser than 100(? How to compare every
element with 100 and how to create subsets )
and I need two vectors y and z s.t
y-c(entries 100)
z-
Dear All,
I have to use loop over an array so I am using following procedure
count-1
repeat{
count-count + 1
c(g[count],1:i[count]) -qw
if(count5)break
}
as a result qw is
[1] 0.9643836 1.000 2.000 3.000 4.000 5.000
[7] 6.000 7.000 8.000
