1-norm - ....ANSWER ....✔✔ Similar to rectilinear
distance; measures the straight-line length of a vector
from the origin. If z=(z1,z2,...,zm) is a vector in an m-
dimensional space, then it's 1-norm is square
root(|𝑧1|+|𝑧2|+⋯+|𝑧𝑚| = |𝑧1|+|𝑧2|+⋯+|𝑧| =
Σm over i=1 |𝑧𝑖|
A/B Testing - ....ANSWER ....✔✔ testing two
alternatives to see which one performs better
2-norm - ....ANSWER ....✔✔ Similar to Euclidian
distance; measures the straight-line length of a vector
from the origin. If z=(z1,z2,...,zm) is a vector in an 𝑚-
dimensional space, then its 2-norm is the same as 1-norm
but everything is squared= square root(Σm over i=1
(|𝑧𝑖|)^2)

Accuracy - ....ANSWER ....✔✔ Fraction of data points
correctly classified by a model; equal to TP+TN /
TP+FP+TN+FN
Action - ....ANSWER ....✔✔ In ARENA, something that
is done to an entity.
Additive Seasonality - ....ANSWER ....✔✔ Seasonal
effect that is added to a baseline value (for example,
"the temperature in June is 10 degrees above the
annual baseline").
Adjusted R-squared - ....ANSWER ....✔✔ Variant of
R2 that encourages simpler models by penalizing the
use of too many variables.
AIC - ....ANSWER ....✔✔ Akaike information criterion-
Model selection technique that trades off between
model fit and model complexity. When comparing
models, the model with lower AIC is preferred.
Generally penalizes complexity less than BIC.
Algorithm - ....ANSWER ....✔✔ Step-by-step
procedure designed to carry out a task.
,3|Page
Analysis of Variance/ANOVA - ....ANSWER ....✔✔
Statistical method for dividing the variation in
observations among different sources.
Approximate dynamic program - ....ANSWER ....✔✔
Dynamic programming model where the value functions
are approximated.
Arc - ....ANSWER ....✔✔ Connection between two
nodes/vertices in a network. In a network model, there is
a variable for each arc, equal to the amount of flow on
the arc, and (optionally) a capacity constraint on the
arc's flow. Also called an edge.
Area under the curve (AUC) - ....ANSWER ....✔✔
Area under the ROC curve; an estimate of the
classification model's accuracy. Also called concordance
index.
ARIMA - ....ANSWER ....✔✔ Autoregressive
integrated moving average.
, 4|Page
Arrival Rate - ....ANSWER ....✔✔ Expected number of
arrivals of people, things, etc. per unit time -- for
example, the expected number of truck deliveries per
hour to a warehouse.
Assignment Problem - ....ANSWER ....✔✔ Network
optimization model with two sets of nodes, that finds the
best way to assign each node in one set to each node in
the other set.
Attribute - ....ANSWER ....✔✔ A characteristic or
measurement - for example, a person's height or the
color of a car. Generally interchangeable with
"feature", and often with "covariate" or "predictor". In
the standard tabular format, a column of data.
Autoregression - ....ANSWER ....✔✔ Regression
technique using past values of time series data as
predictors of future values.
Autoregressive integrated moving average (ARIMA) -
....ANSWER ....✔✔ Time series model that uses
differences between observations when data is
nonstationary. Also called Box-Jenkins.
