[討論] chi2gof的使用

[scorpionyim (小合)]

x=load('datain.txt');
[h1,p1,st1] = chi2gof(x,'cdf',@(z)normcdf(z,mean(x),std(x)),'nbins',2);
[h2,p2,st2] = chi2gof(x,'cdf',@(z)normcdf(z,mean(x),std(x)),'nparams',2);

h1 =
     0
p1 =
    0.9424
st1 =
    chi2stat: 0.0052
          df: 1
       edges: [-334.4347 -106.7901 120.8544]
           O: [23 22]
           E: [22.7578 22.2422]

h2 =
     0
p2 =
   NaN
st2 =
    chi2stat: 0.0052
          df: 0
       edges: [-334.4347 -106.7901 120.8544]
           O: [23 22]
           E: [22.7578 22.2422]

想請問這兩行程式碼中的nbins和nparams差在哪邊?
使用前者p有值，使用後者ｐ則是NaN
跪求幫忙，感恩不盡！！！
