HI;   Please, I will also like to know if it is possible or advisable to save the sub folders; errors, input, output and programs into a new folder(that will be created by me)? ... View more

Hi @Patrick , this is very helpful, thank you.   I have one last clarification to make, please. If the question says $2000 is invested each year, does that not mean that the value of PV should increment by 2000 for the three years 2000, 4000, and 6000, rather than remain 2000? ... View more

@LinusH  Sorry for the late reply. I'm not sure but these questions will help, can you please take me through the logic for each question🙏.    Q1. On January 1 of each year, $5,000 is invested in an account. Determine the value of the account after three years based on a constant annual interest rate of 7.5 percent.   Q2. Compare the interest for yearly versus quarterly compounding on a $50,000 investment made for one year at 7.5 percent interest. How much money will a person accrue in each situation?   Q2b. What if you wanted to determine the quarterly compounded interest after a period of 20 years (80 quarters)?   Q3.  Compute the total amount of money you will have if you start with $100 and invest it at a 3.75% interest rate for 3years.   Q4. A new account was opened in the SBI with initial deposit of Rs. 10,000/. SBI offers an interest rate of 4%. Find the balance after 5 years. Also store the every year and the balance(Saw this on the community but logic was not explained).   Thank You. ... View more

@LinusH  Thank you for the reply. In the first program for instance, the rate was not divided by 12 unlike the second one, what does this imply? In some cases the rate was divided by 12 within the loop, for some other it was outside the loop, what difference will this make?   Secondly, where interest is calculated separately, we have capital+interest, in another program we have earned+capital+interest, earned being the accumulating variable in the sum statement.   In the last program, the interest was not calculated separately; Earned+(capital+earned)*rate.   Since each solution gives entirely different answers, it would mean they address different Questions, I'm trying to figure the sort of questions that apply to each program.   If I'm given a question on do loop, I won't be sure which method is correct because I don't get the logic.   Thank you.   ...

@Rick_SAS  It simply replaces the scatter plot. I actually want both to appear. Thanks. ... View more

Hi, @Rick_SAS  @Quentin  @ballardw @   I was able to overlay the two plots, but because I specified two different group values in the scatter statement(group=serostatus) vbox statement (group=cytokine), the legend of the@ cytokine was overridden... I want both legend for cytokine and serostatus to appear at the bottom of the graph.   The serostatus variable contains seropositve and seronegative, I want them to have two distinct symbools, square and circle respectively. I specified the markerattrs= option twice but only the second displays which is square, how can I achive this?   Thanks.   proc sgpanel data=simu2;   /* Use the SORT= option to order the panels */   panelby strain agegrp  /  rows=2 columns=4 layout=lattice  COLHEADERPOS=bottom sort=ascending uniscale=column novarname START=BOTTOMLEFT NOBORDER;   styleattrs datacolors=(rose green aqua purple);   scatter x=visit y=med_iqr / name="scatter"   group=serostatus name="a" jitter markerattrs=(size=6px symbol=circle)    markerattrs=(color=CX4F4F4F symbol=square size=5px)  name="a" jitter;           /**markerattrs=(symbol=circle size=6px) jitter       markerfillattrs=(color=black)       markeroutlineattrs=(color=black)       transparency=0.5;*/   vbox med_iqr / category=visit name= "b" group=cytokine fill  BOXWIDTH=0.8            lineattrs=(color=black thickness=1)       whiskerattrs=(color=black thickness=1)       medianattrs=(color=black thickness=1);     rowaxis values=(0.00001 0.5 1 1.5) valuesdisplay=("0.1" "0.3" "1.0") label="CD8+ T cells(%)*Median(IQR)";   colaxis values=("Baseline" "Day 64" "Day 120" "Day 360") grid display=(nolabel);       run; ...
