How to calculate the expected value of sample information (evsi )<br>Calculate the expected monetary value (emv) of each alternative action. Note which is the emv * (greatest value). Determine the likelihood probabilities.
The likelihood probabilities can change over time.
( z1 possible :ARG1 ( z2 change :ARG1 ( z3 probability :mod ( z4 likelihood ) ) :mod ( z5 over-time ) ) )
