[Scilab-users] simulated binomial is shifted to the left

[Rafael Guerra]

Defining an appropriate x-axis support for plot2d and binomial helps:

// START OF CODE
clf;
p=[0.1176471    0.2352941    0.0588235    0.3882353    0.2];
N=100;
for i=1:5;
    histplot(0:60,grand(1,10000,"bin",N,p(i)),style=i);
    x = linspace(-0.5,N-0.5,N+1)
    plot2d(x,binomial(p(i),N),style=i,rect=[0 0 60 .175]);
end;
// END OF CODE

Rafael

Subject: [Scilab-users] simulated binomial is shifted to the left

When I compare Monte-Carlo simulated binomial distributions with the respective analytical binomial distributions, the histplot of the simulated ones is shifted to the left. What am I doing wrong?

SciLab code:
p=[0.1176471    0.2352941    0.0588235    0.3882353    0.2]; N=100;
for i=1:5;histplot(0:60,grand(1,10000,"bin",N,p(i)),style=i);plot2d(binomial(p(i),N),style=i,rect=[0 0 60 .175]);end;
