Hello,

The logitfit function in Stixbox needs to be corrected

1. I corrected line 29 from

```auto
if or(abs(one-x*x\one)>0.0000000001) then

```

to

```auto
if or(abs(one-x.*x\one)>0.0000000001) then

```

1. I corrected line 30 from

```auto
fprintf(' Intercept column added \n ');

```

to

```auto
mprintf(' Intercept column added \n ');

```

1. Line 44 also need to be corrected

```auto
ddf = 1 ./ (g0+g1)*ones(1,nb) .* x'*x;

```

but I have not found the right way to correct that line

Can anyone help me?

BR
