Deal list
I want to generate a random number in an interval using exponential low
I know how to make that simply using uniform low
x1 - runif(1, 5.0, 7.5)
this will generate a number between 5 et 7.5 but with uniform low.
Could you help pease.?

the distances alone it would be enough, except that the height returns
the distance all the way to 0, rather than to the adjacent merge. So,

Estimated a model based on common data (you can find it in R library), and
I wanted to plot the orginal values with the estimated one. Unfortunately
I can only see the original values.
Below is the code with data library:
/
According to the example of logistic.display:
model0 - glm(case ~ induced + spontaneous, family=binomial, data=infert)
summary(model0)
logistic.display(model0)
induced: 3levels 0,1,2
spontaneous: 3levels 0,1,2
So if 0 is reference, we should get 2 OR for induced1, induced2,
spontaneous1,
Hi
Please any one help in finding the predicted value for lmer function
model- lmer(formula =formula,data=data,verbose=TRUE,family = gaussian)
I need to get predicted value for this model.
I'm not able to get the formula
Please help
Thanks in advance

Hello Hasan Diwan:
The codes you gave, download Yahoo quotes to Excel spreadsheet, works well
in my pc, too. Thank you
so much.
As a novice of R language, I did find that one sentence works in one
package usually is not available in
another package. To some reason, I am using
Yes,I¡¡understand.
Thanks for your help.

Hi lm_mengxin,
If that's the case, just use as.factor():
fit - glm(case ~ as.factor(induced) + as.factor(spontaneous),
family=binomial, data=infert)
logistic.display(fit)
Sir:
I find out that for 2 level factor, if I set it to factor, then I'll get
error reply.
For the instance last mail, if I use:
result1-glm(y ~ gender,family = binomial);#gender has 2 levels
logistic.display(result1)
Error in coeff[, 1] : incorrect number of dimensions
if I use:
lm_mengxin,
Yes, it happens because you are not following what Dr. Chongsuvivatwong
suggested you in a previous email. Compare
yourdata$age1 - factor(yourdata$gender)
result1-glm(y ~ gender + CD4,family = binomial, data=yourdata)
logistic.display(result1)
and
fit -glm(y ~
