According to time,

If you effort to spend less than 8 hours per day, you live worse life now.

If you effort to spend more than 8 hours per day, you live like animal life now.

If you effort to spend more than 8 hours and focus, etc per day, you will achieve your dream.

One of the human character is that sleep more and play something and more comfortable.

So we always effort to spend more than eight hours for improving our ability.

When you have a meetting with someone, you should arrive there before 5 minutes.

You need to set your body condition for studying or working.

Statistics is using many areas that Economics, Engineering, Sprots, Business.

We operated Static Programme.

We typed that "sysuse auto", "su price", "mean price", "mean price, over(foreign)" and opened some files.

5주차

Today we learned about how to describe 'Stata Programme' and studied 'Statistics for Business and Economics' in the class.

Unfortunately, we can't know our future. so we should prepare about it.

We should change and do training ourselves every day for a better life.

Nowadays it is the information age, when we get a job.

Many company need who have computer skills.

So we need to study it. it is not just in paper book.

6주차

Today we studied about the probability.

There is the probability in many area like Mathematics or Sciences.

We can know the probability of Mathematics in the analysis.

But we can't know the probability of Sciences in the exact value.

According to technological development, importance of Mathematics is increased greatly.

We must stay to awake that think critically everything.

7주차

Today we studied about Sampling Distributions.

We practiced how to use Stata Pragramme.

We entered site that http://kastata.org/menu7_1.php and downloaded second file.

We typed "tab abany" , "tab abany, nolabel" , "recode abany (2=0), gen(abany1)".

We opened Proportion test in Statistics category.

Some people do for their's goal hard and diligently but they don't come true.

Why they don't do that.

Unfortunately, It is mismatch that study in the school and need in the society.

The human is different from the animal.

The animal live just for survival.

The human live trying to something constantly for better life.

Today I attend the class late because I handed my task in.

Korea just spend too much time to learned grammar and reading skill for exam.

But they can't talk with foreigner.

We must use English in daily life.

We treated 'Stata Programme' in data7_3 and data2_2.

It was difficult to me.

We should practice it in any form when we need it.

10주차

We should make a goal and choose a way for achievement.

Today we studied about "Inferences Based on Two Samples".

There are two samples, what is a difference each other.

We practiced "Stata program" and opened "Data4_1"

We typed "twoway(scatter write read) (scatter math read, msymbol (square_hollw))".

It can be able to see a correlation each other.

But my computer wasn't installed "Stata program". my left computer wasn't working keyboard.

Sorry about that.

11주차

Today we learned about theory of urban planning.

Planning theory has been constantly changing such as choice theory, advocacy theory, pluralism, transactive theory.

We must set goals in life and find the problem.

We need to know what is the best alternative after then.

We need to reduce the error as possible as.

We treated stata program using the data 8-1 and 4-1.

It was difficult to me.

So I will study and practice that program.

Today we learned about Inference based on teo sample.

When most students study to something, they act repeatedly such as forgetting and memorization.

We need to study constantly in daily.

We opened that R_data5_1, R_data6_1 and typed command that

1. db alpha

2. recode lottery(1/10=1) (11/20=2) (21/30=3) (31/40=4) (41/50=5) (51/60=6) (61/70=7) (71/80=8) (81/90=9) (91/100=10) , gen(lottery_grp)

3. tab lottery_grp

4. findit mgof

5. mgof lottery_grp, freq

6. ssc install moremata

7. mgof lottery_grp, freq

It was too long and difficult but if you know a way how to treat stata program.

you can compare data convenient and easy.

14주차

Today we studied about that simple linear regression.

1. Describe the linear regression model.

2. State the regression modeling steps.

3. Explain ordinary least squares.

4. Compute regression coefficients.

5. Predict response variable.

6. Interpret computer output.

Model types are deterministic models and probabilistic models.

It is able to predict and estimate.

English is important everything.

So we should study hard everyday.

We opened R_data 8_1.

We can type command or just click command.

15주차

Today we studied about that multiple regression and model building.

1. Explain the linear multiple regression model.

2. Test overall significance.

3. Describe various types of models.

4. Evaluate portions of a regression model.

5. Interpret linear multiple regression computer output.

6. Describe stepwise regression.

7. Explain Residual analysis.

8. Describe regression pitfalls.

The regression model use for prediction and estimation.

Math is very important in analysis.

English is also important to stata program.

We opened R_data 8_2 and typed that reg csat percent income.

Next week is final exam.

It can set exam questions about stata program.

So we should prepare about that.
