plot interaction with error bars

Ameurgen — Fri, 14 Apr 2023 15:30:48 GMT

Hi Sas community;

I need help to plot my output LSMEANS form proc hpmixed , your can comment the code below , for the first plot estimate vs DAMDIM (Axe1) and Mean for AXe2 its work using proc gplot , but when i used interaction BHB*DAMDIM, i cant figure out how the plot should be, alos, i am thing to plot them seperately but i don't now .

Thank you for your helping me

********************************************

without interaction

/* Dam days in milk effect **/
data lsmns12;
set lsmns11;
IF (Effect eq 'Dam_DIM');
Dam_DIM = Dam_DIM ;
mean = Estimate;
output;
mean = Estimate - StdErr;
output;
mean = Estimate + StdErr;
output;
run;

/***/
axis1 order=(30 to 240 by 10);
axis2 label=(angle=90) order=(1.5 to 2.6 by 0.1);
symbol1 interpol=none color=blue value=dot line=2 ;
symbol2 interpol=hiloctj color=red line=1 height=1.5;

title 'daughter Total Services vs dam_days_in_milk at daughter conception, Parity 1';
proc gplot data=lsmns12;
plot Estimate *Dam_DIM/vaxis=axis2 haxis=axis1 ;
plot2 Mean*Dam_DIM/vaxis=axis2 ;
run;
quit;

Thank you

You don't really say what PROC you use to estimate the interactions, and obtain error estimates from — which are needed to get confidence interval "error bars". That information would be very helpful. Nevertheless, the EFFECTPLOT statement in many PROCs can do this (example).

Hi sir,

Its mentionned i used proc hpmixed fro my muxed model analysis, the interaction is estimate by lsmeans function, i create the mean +/- estimate to output my lower and upper limit. all detail are in the shared code. but i will look at your propositon effectplot , which i thing good alternative

Thank you sir for youyr help
