  • \(\ST_0= 1\) if Suzy puts, 0 if you don’t
  • \(\BT_1= 1\) if Billy leaves, 0 or even
  • \(\BS_dos = 1\) in the event the bottles shatters, 0 if you don’t

\PP(\BT_1= 1 \mid \ST_0= 1) <> = .1 \\ \PP(\BT_1= 1 \mid \ST_0= 0) <> = .9 \\[1ex] \PP(\BS_2= 1 \mid \ST_0= 1 \amp \BT_1= 1) <> = .95\\ \PP(\BS_2= 1 \mid \ST_0= 1 \amp \BT_1= 0) <> = .5\\ \PP(\BS_2= 1 \mid \ST_0= 0 \amp \BT_1= 1) <> = .9\\ \PP(\BS_2= 1 \mid \ST_0= 0 \amp \BT_1= 0) <> = .01\\ \end

But in truth these two likelihood is equal to

\]

(Remember that you will find additional a small opportunities to your bottles in order to shatter because of some other end up in, even if neither Suzy neither Billy place the stone. It implies that the number of choices of all tasks out of philosophy to the latest variables was self-confident.) Brand new related graph is shown when you look at the Figure nine.

\PP(\BS_2= 1 \mid \do(\ST_0= 1) \amp \do(\BT_1= 0)) <> = .5\\ \PP(\BS_2= 1 \mid \do(\ST_0= 0) \amp \do(\BT_1= 0)) <> = .01\\ \end

However in reality both of these odds is comparable to

\]

Carrying fixed one to Billy doesnt put, Suzys place raises the chances your package have a tendency to shatter. Ergo the standards was came across having \(\ST = 1\) is an authentic cause of \(\BS = 1\).

  • \(\ST_0= 1\) in the event that Suzy puts, 0 otherwise
  • \(\BT_0= 1\) in the event that Billy puts, 0 otherwise
  • \(\SH_1= 1\) in the event the Suzys stone strikes this new bottle, 0 or even
  • \(\BH_1= 1\) when the Billys material moves the new bottles, 0 or even
  • \(\BS_2= 1\) in case your bottle shatters, 0 if not

\PP(\SH_1= 1 \mid \ST_0= 1) <> = .5\\ \PP(\SH_1= 1 \mid \ST_0= 0) <> = .01\\[2ex] \PP(\BH_1= 1 \mid \BT_0= 1) <> = .9\\ \PP(\BH_1= 1 \mid \BT_0= 0) <> = .01\\[2ex] \PP(\BS_2= 1 \mid \SH_1= 1 \amp \BH_1= 1) <> = .998 \\ \PP(\BS_2= 1 \mid \SH_1= 1 \amp \BH_1= 0) <> = .95\\ \PP(\BS_2= 1 \mid \SH_1= 0 \amp \BH_1= 1) <> = .95 \\ \PP(\BS_2= 1 \mid \SH_1= 0 \amp \BH_1= 0) <> = .01\\ \end

However in fact those two chances is actually equivalent to

\]

Because the in advance of, i’ve assigned chances alongside, but not equivalent to, no plus one for the majority of of your choice. New graph was shown during the Shape ten.

We wish to demonstrate that \(\BT_0= 1\) is not an authentic reason behind \(\BS_2= 1\) according to F-Grams. We shall show which in the shape of an issue: was \(\BH_1\during the \bW\) or is \(\BH_1\within the \bZ\)?

Imagine basic one to \(\BH_1\within the \bW\). Then, it doesn’t matter if \(\ST_0\) and you may \(\SH_1\) are in \(\bW\) or \(\bZ\), we have to have

\PP(\BS_2 = 1 \mid do(\BT_0= 1, \BH_1= 0, \ST_0= 1, \SH_1= 1))\\ \mathbin <\gt>\PP(\BS_2 = 1 \mid do(\BT_0= 0,\BH_1= 0, \ST_0= 1, \SH_1= 1))\\ \end

But in facts these two likelihood is equal to

\]

95. When we intervene to set \(\BH_1\) to 0, intervening to the \(\BT_0\) makes no difference into the likelihood of \(\BS_2= 1\).

\PP(\BS_2 = local hookup 1 \mid do(\BT_0= 1, \BH_1= 0, \ST_0= 1, \SH_1= 1))\\ \mathbin <\gt>\PP(\BS_2 = 1 \mid do(\BT_0= 0, \ST_0= 1, \SH_1= 1))\\ \end

In fact these two likelihood is equivalent to

\]

(The following opportunities try some big, due to the tiny likelihood you to Billys stone tend to struck in the event he does not toss it.)

Thus whether or not \(\BH_1\in \bW\) or perhaps is \(\BH_1\when you look at the \bZ\), condition F-Grams isn’t satisfied, and you will \(\BT_0= 1\) isn’t evaluated to be an authentic reason for \(\BS_2= 1\). An important idea would be the fact this is not sufficient to own Billys place to raise the likelihood of the fresh new bottles smashing; Billys throw and what the results are later must increase the odds of shattering. As the one thing actually occurred, Billys material overlooked the new package. Billys place together with stone shed doesn’t increase the odds of smashing.
