Hi,
I have a training dataset which has two columns which has around 70 values.
1. PNRNo whose values like UT768G, CXKA, 4IOI59, 4BV7TW...(typical PNR
number patterns)
2. I have created one more factor variable mentioning (IsPNR) - so all
the values are 1 (true)
My first

Hi Everyone,
I have an experimental design that I'm confused about what model/approach I

Thank you David for your answer.

- So, do you think that try to estimate the life expectancy would be risky
and probably not justifiable? Is there some sort of 'confidence' that the
model could give me for a prediction?

Wrong list. This list is about R, not about statistics/statistical

Hi Aureus,
I think you have cut and pasted the text in the console window when
you say saving to text. One way to get the entire output of your

sink('simper_test.txt)
# run your test code here
sink()
The output will be in the file simper_test.txt
