    Data sets in txt form

    (date discussed in class)  Programs
    (20211007)  SetUp(1) SetUp(1) shows you how to:
    1. devide graphical windows (not necessary if using R studio where you use the left program with extension .r)
    2. assign variables/sequences
    3. plot and make titles for the graph
    4. generate normally distributed observations/make histograms
    5. do simple regressions and related plots  (you should see the effect of sample size and s.d.  on the fitted reg. lines)
    6. quit R
    (2021102 )   SetUp(2)

      ch01ta01 data
    SetUp(2) shows you how to:
    1. scan a data set in your working directory into R
    2. get figures and tables in the textbook with the Toluca Company examples
    3. construct confidence intervals for reg. coeff.'s, confidence/prediction  intervals for the mean response at given predictor x's values
    4. construt conf. band for the entire reg line,
    5. overlay three type of intervals in one plot for better comparison
    6. save the output to a file for preparing your homework, or save the R commands for later use
    (20211123)  MLR

    ch06fi05 data
    MLR shows you how to
    1. some basic matrix operations in R,
    2. how to obtain the design matrix after fitting a simple linear regression model,

    With the Dwaine Studios examples
    3. do multiple linear regression
    4. get figures and tables in the textbook
    5. make basic scatter plots for M-L-R data analysis
    6. obtain the design matrix
    7. get (simultaneous) conf. intervals for reg. coefficients,  confidence/prediction  intervals for the mean response at given predictors's values

    ch6pr18 data
    GLT shows you how to
    1. obtain SSEs from the full model and the reduced model
    2. obtain F(1-alpha; m, k) in R
    3. use the general linear test approach  for testing certain hypotheses (by giving 3 examples)
    (20211223) ResidPlot This program ResidPlot
    1.  let you get a feeling as how a random sample of size n from N(0, 1) would look like in time sequence plots, and in histograms;
    2. with simulated regression data.....  shows you some basic residual-plots for diagnostic in a regression analysis
    Please note that how a violation of certain assumptions made in reg model affect the display........
    (20220104/6) WLSE

    ch11ta01 data
    WLSE shows you how to do W.L.S.E. when non-constant variances occurs......
    esp. shows you how to get  figures and tables in the textbook with Blood Pressure Example on p427 .

    ch3ta10 data
    This program varstabtrans illustrates a complete process when analyzing a real data set with nonconstant variance problem........
    Instead on using W.L.S.E. (which is covered in WLSE), we try transformations when nonconstant variances occur in this program.
    We run through the Case Example -- Plutonium Measurement on p 141 of textbook.
    Esp. you learn how to delete some data points from a data set, how to update model , and how to get basic diaqnostics residual plots.

    Problems  (作 業成績10%由各組派一代表和助教面試講解一題要用R程式回答的問題;題目採先選先贏制,講過題目其他組不得再選擇喔)
    Due date
    0106 Ch.3 : 9

    In R, sum((fitted.values(fm)-mean(y))^2)
    , sum(residuals(fm)^2) give you SSR and SSE, respectively;
    where y denotes the response variable and fm is the fitted model obtained from lm(y~.....)

    Ch.10 :

    Ch.11 : 6 (a~f), 7(a~f), 13, 17
    這 份作業不用交。
    但,同學 一 定  要  自 己  做過這些題目喔
    1228 NOTE: When asked to draw a dot plot in this homework, you may draw the stem-and-leaf plot, instead. 
    In R, stem(x)
    gives you the stem-and-leaf plot of data in x.
    Ch.3 :
    3 (a, b, c, d.) (For d, only need to prepare a normal probability plot, i.e. the Q-Q plot)
             4 (a, b, c, d, e, f, h) (For e, only need to prepare a normal probability plot, i.e. the Q-Q plot)
            6 (a, b, c.) ( For c, only need the Q-Q plot)
            8 (a, b, c, d). ( Only Q-Q plot for d)
