Almost after 2 years and some 3 months I am going for a visit to place where I stayed at hostel for the first time. I was too scared at the name of hostel and all those stuff after class 12th; but Banasthali was like none of those scary things. The most special thing is the warmth shared by 2 persons, whether it be roommates or a hostellite and warden. What I have missed most about it is hostel life and the friends. We somehow had a sort of family with no bounds. Room appeared to be home.. When I came to Pune, I enjoyed every bit of it, the department, new batchmates, trips, freedom to be what you want, talk on phone; but could not have friends like those.
A chance to see all of them again. I hope I will make most out of these 4 days.. :)

Bayesians have their own ways
IDRS - 2
Neelabh Rohan on Information Criteria for Bayesian's
Under classical setup for choosing models we use AIC and BIC criteria. But these involve likelihood which further takes the parameter as constant. But if we are defining model with prior distribution for parameter itself (that is where Bayesian comes into picture), then we cannot use the usual likelihood and hence criteria fail.
The first one is Deviance Information Criteria, given by Spiegelhalter (2000) in JRSS, which considers the model complexity (in terms of number of parameters) at the same time the usual -2log L term (which involves posterior estimate of the parameter).
The Focused Information criteria, given by Claskens and Hjort (2003) in JASA, considers only those parameters (or their functions) which are in focus, instead of taking all. This criteria is there for both frequentists as well as Bayesians. We have some fixed parameters (narrow part of model) and some parameters which keep changing (the wide part of it). So using the information matrices for these vector parameters a criteria is being formulated.
PS 1: The beauty of these criterias is that they can handle the models which have varying number of parameters.
PS 2: I will miss the next session. :(

in the end it's right
So I got answers to all my Whys..
Key is to accept people as they are. They are not I, that they should be like me, behave in the manner I like. It doesn’t makes sense in expecting others to behave in the way I do. The best way is to accept a person with his individuality. And not only others but it is important to accept the own self as a unique being.
Sometimes unknowingly I get hurt by some acts of others; but then it is not because they are unkind, or impolite, or they want to hurt me. Its just because their ways are like that; may be their culture or upbringing.
They are just simple friends, so best way is not to bother my mind, because that cannot change them or their habits or their thinking. Only thing I can change is my own point of view towards them..
because...
Another turning point, a fork stuck in the road
Time grabs you by the wrist, directs you where to go
So make the best of this test, and don't ask why
It's not a question, but a lesson learned in time
It's something unpredictable, but in the end it's right.
I hope you had the time of your life.
So take the photographs, and still frames in your mind
Hang it on a shelf in good health and good time
Tattoos of memories and dead skin on trial
For what it's worth it was worth all the while
It's something unpredictable, but in the end it's right.
I hope you had the time of your life.

I want to have time of my life ...so :)
PS: Thanks Maryam.

Why?
Why is it so that, everything is alright but still something in everything is stuck?
Why I am clueless about how 24 hrs go away, despite of the fact that neither I am sleeping much nor I am procastinating work?
Why the air in the room is bit weird and uncomfortable?
Why sometimes we are not able to handle even the formatting of simple forms on IE, and waste almost 2 hrs on that?
Why don't people keep their words instead of having an excuse ready everytime?
Why do they think that to fool someone is that easy?
Why does it always have to rain only at the time when I am longing for a walk?
Why don't clouds pour down and empty their heart when they are full of water, and rain would be comforting them?
Why urgency for pouring down goes away as soon as we are able to pen down?
Why should this post make sense to anyone who is reading this?

Informal Discussions for Research Students
IDRS - I
Dr.T V Ramanathan on Edgeworth Expansion
As TVR said this series is being started for the third time, as for the first two it was forced to stop due to lack of speakers. He is quite hopeful that its not going to happen again, and I stand with him.
This Saturday Sir initiated, on Edgeworth Expansion. Applications sound interesting. How we could go ahead of Central Limit Theorem before assuming Asymptotic Normality. Expressions may seem bit clumsy, but then we it gives us more confidence in the inference we draw.
Due to Vaishali's very very heavy Cheese Mysore Masala Dosa, I expected myself of having a doze in the lecture. But as usual TVR's enthusiasm is best at keeping me awake.
I hope IDRS will keep going this time.

Sunday
"Can you tell me why people go to such lengths to hide their selves? Or why I always behave very differently when I'm in the company of others? Why do people have so little trust in one another? I know there must be a reason, but sometimes I think it's horrible that you can't ever confide in anyone, not even those closest to you."
-The Diary of a Young Girl
Its a bit hard to imagine how a girl who is just 13 years old thinks so much about human nature. May be these are circumstances, which are responsible for our emotional growth, and it is not directly related to physical growth.
Apart from reading Sunday was cool. It started with 3-4 hours of work, which i did to compile the details for discussion with Sir. Later was bit upset about not being able to go to Nanak Darbar.
But with F.R.I.E.N.D.S. and then a good sleep followed by evening walk in cool breeze, made my weekend to end nicely..

paper is more patient than people
In spite of the length of my to do list (which includes tasks from my research guide who keeps on increasing the length whenevr I see him.. and the project head who is adding to it, with latest one to make a annual report of project which I have joined just 50 days ago...) I have been reading lately Anne Frank's The Diary of a young Girl (title of this post comes from it). I personally feel that actually no one on earth has got patience for listening to someone when shes speaking out all her heart. Atleast when its a chatter box like me. Theres lot more freedom to write on paper. Freedom to say anything. But then why I found blogging as better option than writing on diary? May be after 4-5 failed attempts to start writing regularly I have lost all interest to try it once again.
And then when I write its me all alone. But this way I virtually feel that I am sorrounded by people.
To my irritation I have not been able to finish these 427 pages. Its almost a month since I started. Theres lot to do, and another reason to hurry is my plans for vacation in the next month.
Yesterday night while going through I liked these lines from the book,
"You can be lonely even when you're loved by many people, since you're still not anybody's 'one and only '",
and somehow I agreed.

Keep Smiling Forever
.jpg)
so my little brother...though now you are no more as little as in this old memory...you will be a year older today. Times have changed and we are far apart, but over this distance we have become closer, as the time passes by. Always trusted you, and and have shared every secret,wish we will always have the same warmth in our relation.Wishing you all smiles and joys forever.
A Very Happy Birthday.

this is one fine day
I did not realise that this could be that special. Today when Neelabh came up with his dissertation ready, there was something extraordinary about it. I thought this would be like any other usual moment, when we are happy about somethings. But no this wasn't like that. There is some special glitter in the eyes ...some contentment. As if the dissertation cover and he was on contest on whos gonna excel out.
And looking all this I realised the hard work behind, which gives this spirit, and way to singular smile...so that the small problems we face in the journey don't seem anything when once we have 'that' in hand.
:)
