dec_cor
is a frequency that describes the
number of individuals in the current population N
for which the decision is correct/accurate
(i.e., cases in which the decision corresponds to the condition).
Details
Key relationships:
to probabilities: The frequency of
dec_cor
individuals depends on the population sizeN
and the accuracyacc
.to other frequencies: In a population of size
N
the following relationships hold:correspondence: When not rounding the frequencies of
freq
thendec_cor = N x acc = hi + cr
(i.e.,
dec_cor
corresponds to the sum of true positiveshi
and true negativescr
.
Current frequency information is computed by
comp_freq
and contained in a list
freq
.
