Paul Sharp, the lead author, noticed two errors in the naming of variables in two the key equations in the article.

Equation 6 is incorrect. The equation in the published article read::

\begin{array}{ll} [\begin{array}{ll} Q_{M B_{t + 1}} (p r e s s = g) \\ Q_{M B_{t + 1}} (p r e s s = j) \end{array}] \\ = [\begin{array}{ll} β_{M B r e w a r d} P (f = r e w a r d | p r e s s = g)_{t} & β_{M B p u n i s h} P (f = p u n i s h | p r e s s = g)_{t} \\ β_{M B r e w a r d} P (f = r e w a r d | p r e s s = j)_{t} & β_{M B p u n i s h} P (f = p u n i s h | p r e s s = j)_{t} \end{array}] [\begin{matrix} 0 \\ - 1 \end{matrix}] \end{array}

The correction to equation (6) is as follows:

\begin{array}{ll} [\begin{array}{ll} Q_{G P_{t + 1}} (p r e s s = g) \\ Q_{G P_{t + 1}} (p r e s s = j) \end{array}] \\ = [\begin{array}{ll} β_{G P r e w a r d} P (f = r e w a r d | a = p r e s s g)_{t} & β_{G P p u n i s h} P (f = p u n i s h | a = p r e s s g)_{t} \\ β_{G P r e w a r d} P (f = r e w a r d | a = p r e s s j)_{t} & β_{G P p u n i s h} P (f = p u n i s h | a = p r e s s j)_{t} \end{array}] \end{array}

Equation 8 also also had a slight error in how the action variable was named. It is now consistent with how all other equations reflect the action taken. The original equation in the article was:

P (a = p r e s s j) = \frac{e^{Q_{I n t e g r a t e d} (p r e s s = j)}}{e^{Q_{I n t e g r a t e d} (p r e s s = j)} + e^{Q_{I n t e g r a t e d} (p r e s s = g)}}

The equation is now correction to read:

P (p r e s s = j) = \frac{e^{Q_{I n t e g r a t e d} (p r e s s = j)}}{e^{Q_{I n t e g r a t e d} (p r e s s = j)} + e^{Q_{I n t e g r a t e d} (p r e s s = g)}}

We apologize for any confusion this might have caused.
