posthoc - Post hoc tukey test for two way mixed model ANOVA -

-

i , of students have searched solution in numerous places no luck , literally months. keep on being referred lme command not want use. output provided not 1 colleagues or myself have used on 15 years. given using r teaching tool, not flow following t-tests, , one-way anovas intro stats students. conducting 2 way rm anova 1 factor repetition. have succeeded in getting r replicate sigmaplot gives main effects. post hoc analysis given r differs same post hoc in sigmaplot. here code used - notes (as using teach students).

#iv between: ivb1 - independent variable - between subject factor #iv within: ivw1  - independent variable - within subject factor #dv: dv           - dependent variable.  aov1= aov(dv ~ ivb1*ivw1 + error(subject/ivw1)+(ivb1), data=objectl) summary(aov1)  # post hoc analysis ph1=tukeyhsd(aov(dv ~ ivb1*ivw1, data=objectl)) ph1

i hope can help. thank you!

i have had problem , find convenient alternative aov_ez() function afex package instead of aov(), , performed post hoc analysis using lsmeans() instead of tukeyhsd():

model <- aov_ez(data,                                        id="subjid",                                  dv="dv",                                      within=c("ivw1", "ivw2"),              between = "ivb1")  # post hoc comp = lsmeans(model,specs = ~ ivb1: ivw1: ivw2, adjust = "tukey") contrast(comp,method="pairwise")

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
