Hi, So I hope to plot a curve of dots and lines connecting the dots, and below is my code. I am new to SAS and I wonder if the problem is due to the use of iml here. I also pasted the error log below. proc iml;
delta = do(0, 16, 2);
alpha = 0.1;
z_half_alpha = quantile('NORMAL', 1-(alpha/2));
n = 10;
sigma = 8;
y = 1 - cdf('NORMAL', (z_half_alpha - delta)/sqrt(2*(sigma**2)/n)) + cdf('NORMAL', (- z_half_alpha - delta)/sqrt(2*(sigma**2)/n));
create q5_data var {delta y}; append; close q5_data;
symbol1 v=circle i=sm5; title1 ’Power Curve for Z-test’;
axis1 label=(’prob’);
axis2 label=(’delta’);
proc gplot data = q5_data;
plot y*delta / haxis=axis2
vaxis=axis1
vref=0.95;
run; And this is the log when I run this piece of code on SAS Studio: 1 OPTIONS NONOTES NOSTIMER NOSOURCE NOSYNTAXCHECK; 72 73 proc iml; NOTE: IML Ready 74 delta = do(0, 16, 2); 75 alpha = 0.1; 76 z_half_alpha = quantile('NORMAL', 1-(alpha/2)); 77 n = 10; 78 sigma = 8; 79 y = 1 - cdf('NORMAL', (z_half_alpha - delta)/sqrt(2*(sigma**2)/n)) + cdf('NORMAL', (- z_half_alpha - 79 ! delta)/sqrt(2*(sigma**2)/n)); 80 create q5_data var {delta y}; 80 ! append; 80 ! close q5_data; NOTE: The data set WORK.Q5_DATA has 9 observations and 2 variables. 81 82 symbol1 v=circle i=sm5; title1 ’Power Curve for Z-test’; 82 symbol1 v=circle i=sm5; title1 ’Power Curve for Z-test’; _______ 180 ERROR 180-322: Statement is not valid or it is used out of proper order. 83 axis1 label=(’prob’); 83 axis1 label=(’prob’); _____ 180 ERROR 180-322: Statement is not valid or it is used out of proper order. 84 axis2 label=(’delta’); 84 axis2 label=(’delta’); _____ 180 ERROR 180-322: Statement is not valid or it is used out of proper order.
