al usar Tabular Autocorrelación en el Inspector de objetos se obtienen sólo dos valores (y no los 9 esperados) para la ACF:

1,-0.485278806246
2, 0.379972576628

que no se corresponden con los que saca la funcion AutoCor o los calculados a mano con las fórmulas teóricas para la ACF, que sí coinciden:

1.0,-0.565034828462
2.0,0.381876179936
3.0,-0.144228891348
4.0,-0.0739535186511

working on it,

The difference was that from tolbase the autocov was computed assuming mean 0. That behavior was changed (2005-04-25) in tol but not in toltcl.

[Jorge]

now the default binding on Text is disabled:

[27] Control-k deletes from the insertion cursor to the end of its

line; if the insertion cursor is already at the end of a line,
then Control-k deletes the newline character.

the fix will be available in release 1.1.4, also at trunk.

sorry!!! the last comment should be for bug 447 (working late)

this bug is fixed, now toltcl and tol behave the same regarding AutoCov function.

the fix will be available in release 1.1.4, also at trunk.
