Hi, I guess Time Series Model will be a solution.... but depends on the available backdata.... model needs a good amount of paramiter understanding & may be complicacy(? )....

This Is Not A Joke!  4 THINGS YOU PROBABLY NEVER KNEW  YOUR MOBILE PHONE COULD DO   There are a few things that can be  done in times of grave emergencies.    Your mobile phone can actually be a life saver or an emergency tool for survival.    Check out the things that you can do with it:   FIRST Emergency The Emergency Number worldwide for  Mobile  is 112.    If you find yourself out of the coverage area of   your mobile; network and there is an emergency,  dial 112 and the mobile will search any existing  network to establish the emergency number for you,  and interestingly this number 112 can be dialled  even if the keypad is locked. Try it out.   SECOND  Have you locked your keys in the car? Does your car have remote keyless entry? This may come in handy someday. Good reason to own a cell phone: If you lock your  keys in the car and the spare keys are at home,  call someone at home on their mobile phone  from your cell phone.   Hold your cell phone about a foot from  your car door and have the person  at your home press the unlock button,  holding it near the mobile phone on their end.    Your car will unlock.   Saves someone from having to drive your keys to you.    Distance is no object.  You could be hundreds of miles away,  and if you can reach someone who has the other 'remote' for your car, you can  unlock the doors (or the trunk). Editor's Note: It works fine! We tried it out and it unlocked our car over a mobile phone!'     THIRD Hidden  Battery  Power Imagine your mobile battery is very low.  To activate, press the keys *3370#  Your mobile will restart with this reserve and the  instrument will show a 50% increase in battery.   This reserve will get charged when   you charge your mobile next time.   FOURTH How to disable a STOLEN mobile phone? To check your Mobile phone's serial number,  key in the following digits on your phone: * # 0 6 #   A 15 digit code will appear on the screen.   This number is unique to your handset.    Write it down and keep it somewhere safe.    When your phone get stolen, you can phone your service provider and give them this code.    They will then be able to block your handset  so even if the thief changes the SIM card,  your phone will be totally useless.    You probably won't get your phone back,  but at least you know that whoever stole it  can't use/sell it either.   If everybody does this, there would be no point in people stealing mobile phones. ATM - PIN Number Reversal - Good to Know If you should ever be forced by a robber to withdraw money from an ATM machine, you can  notify the police by entering your PIN # in reverse.    For example, if your pin number is 1234, then you would put in 4321.   The ATM system recognizes that your PIN number is backwards from the ATM card you placed in the machine.    The machine will still give you the money you requested,  but unknown to the robber, the police will be  immediately dispatched to the location.   This information was recently broadcast on CTV by Crime Stoppers  however it is seldom used because people just don't know about it.  Please pass this along to everyone. This is the kind of information people don't mind receiving, so pass it on to your family and friends People will forget what you said, People will forget what you did, But people will never forget how you made them feel"

Review questions that I wasn't able to get answers to. I would like
to know if I did them correctly or not, please help.

1) If a distribution of the scores of one variable changes
across the categories of another variable, the variables

1. Are associated to some extent
2. Are indicators of the same concept
3. Have a cause and effect relationship
4. Are perfectly associated

2) Conventionally, each column of a bivariate table represents:

1. The highest scores of each variable
2. A category of the independent variable (X)
3. A category of the dependent variable (Y)
4. The lowest scores on each variable

3) For variables measured at the nominal level, measures of
association will have a lower limit of ________ and an upper limit
of ________

1. 0 … 100
2. –1 … +1
3. 0 … 1
4. 1 … 0

4) Cramer's V is

1. Used for tables that are larger than 2x2
2. Based on chi square
3. Easy to calculate
4. All of the above

5) For a 3x3 table, the appropriate chi square measure of
association would be

1. Cramer's V
2. Phi
3. Lambda
4. Gamma

Scott,

Someone reminded me of the max likelihood estimation.. .its N-1 to
make the equation unbiased so as to avoid underestimating the std. I
understood that...The rational that its there to compensate for
sample size is news to me. The equation works for large samples as
well. Not sure if I follow your logic aside from the fact that
mathematically agree with you....a smaller N will give you a bigger
fraction.... but I do not believe that is enough of an explanation. If
that were the case why chose 'N-1' . But thank you for taking the
time to respond.-Amy

Hey people,

I have a question does anyone remember the logic behind the denominator
(N-1) for standard deviation? I need a simpliest terms explanation.
Thanks.
