GLM and REG supports weighted regression with WEIGHTS option.
REG displays tests using HC0, HC3, and White's first and second moment specification test.
Code refactored to cope better with singular or ill-conditioned matrix.
Some unused arguments such as eps (in GLM, REG, aov1, aov2, and aov3) are removed.
e3 arguments are simplified to reduce unnecessary calculation.
corFisher function for correlation test by Fisher's Z transformation is added.
RDmn, RRmn, ORmn use MN weights for point estimates also.
RDmn1 finds confidence interval better.
Some typo fixed.
RDinv, RRinv, ORinv, ORcmh for stratified or meta analysis of 2x2 are added.
GLM reports adjusted R-squared
QuartileRange returns type 2 IQR by default.
UNIV returns also MAD and type 2 IQR.
Coll caculates like SAS not like SPSS
lfit help updated
RD, RR, OR, RDmn1, RRmn1, ORmn1, RDmn, RRmn, ORmn functions for 2x2 table with or without stratification are added.
Description corrected in satt help.
GLM function's arguments changed: SOLUTION to BETA, LSMEANS to EMEAN
ANOVA funciton is removed, because it is almost a duplicate of GLM function.
GLM function's arguments changed.
Descriptive statistics functions such as N, Mean, SD, SEM, Min, Max, Median, UCL, LCL, trimmedMean, Range, QuartileRange, Skweness, SkewnessSE, Kurtosis, KurtosisSE now accept a non-numeric vector that can be converted to a numeric vector.
A bug with no incercept model in
e3 is fixed.
A bug at "adj" option in
LSM fixed, which also affects GLM.
PLOT option related codes are revised.
UNIV added for descriptive statistics
G2SWEEP became faster for large sparse matrix
REG function warns in case of completely aliased model and data and increases epsilon tolerance to 1e-5.
plotDiff option 'Title' removed. Use 'main' option instead.
Descriptive statistic functions (Mean, SD, ...) return NA with inappropriate inputs.
reverse option added to
PLOT option added to
LSM supports grouping when a term is specified.
est support common multiple comparison methods, such as "lsd"(no adj), "bon", "tukey", "scheffe", "duncan", and "dunnett".
ESTM function added.
CONTR function added.
SLICE function added.
satt changed the way of weights calculation. Now, one can give integer weights.
lsm now properly supports models without intercept.
e2 now properly supports single factor models (Type II SS of Oneway ANOVA) without intercept.
Checks inputs and errors during calculation more.
e2 support no intercept model.
GLM handle no intercept model properly.
A column of estimability will be shown when some cofficients are not estimable in
Some errata in help/manual are corrected.
CV (coefficient of variation) in percentage added.
cSS has now
m arguments for non-zero mean hypothesis.
A bug with no intercept model in
Incomplete interaction term names of
LSM does not show estimates which are not estimable, and supports more models
est has more arguments to test estimability
lr0 function for simple linear regressions with each independent variable
lr function for linear regression with g2 inverse
tsum warpper function for
bt function removed to reomove dependency on
NOINT option in REG, ModelMatrix is removed. Use conventional R formula.
Order of coefficients (parameters) changed to be more similar to SAS.
EMS has different arguments from T3MS.
GLM function now has
lsm option for least square mean
LSM function added for Least Square Means in SAS
PDIFF to do pairwise comparison
BY function to run functions by levels of a variable
tsum3 functions for the summary table of a continuous dependent variable
bk function to beautify the output of knitr::kable()
bt function to beautify the output of tsum2, tsum3
G2SWEEP function epxplained
regD function optimized
T3MS renamed as
EMS, because it can handle other types also.
CIest function's arguments and return values changed.
regD function added for influence diagnostics
T3test a bug fixed for one row table
CIest added for confidence interval estimation
e3 function revised for RANDOM test functionality
satt added for Satterthwaite approximation
T3MS added for Type 3 Expected Mean Square formula
T3test added for hypothesis test with different error term
Unnecessary lines in source removed
Contrast input for
cSS changed from column vectors to row vectors.
REG can return
lfit result with
Type III SS function improved
Miscellaneous errata corrected
An erratum is fixed
TO DO: Function to be added - e4, aov4
TO DO: Items to be added - R2, R2ADJ - v0.4.1
lr do this.
