ULTIMATE CHEAT SHEET WITH VERIFIED QUESTIONS
AND ANSWERS, LATEST UPDATED CONTENT, AND
THE SECRET FORMULA FOR A GUARANTEED A+ PASS
IN ANALYTICS MODELING.
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| - ANSWER-1-norm
testing two alternatives to see which one performs
better - ANSWER-A/B Testing
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) - ANSWER-2-norm
,2|Page
Fraction of data points correctly classified by a model;
equal to TP+TN / TP+FP+TN+FN - ANSWER-Accuracy
In ARENA, something that is done to an entity. -
ANSWER-Action
Seasonal effect that is added to a baseline value (for
example, "the temperature in June is 10 degrees above
the annual baseline"). - ANSWER-Additive Seasonality
Variant of R2 that encourages simpler models by
penalizing the use of too many variables. - ANSWER-
Adjusted R-squared
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. -
ANSWER-AIC
,3|Page
Step-by-step procedure designed to carry out a task. -
ANSWER-Algorithm
Statistical method for dividing the variation in
observations among different sources. - ANSWER-
Analysis of Variance/ANOVA
Dynamic programming model where the value functions
are approximated. - ANSWER-Approximate dynamic
program
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.
- ANSWER-Arc
Area under the ROC curve; an estimate of the
classification model's accuracy. Also called concordance
index. - ANSWER-Area under the curve (AUC)
, 4|Page
Autoregressive integrated moving average. - ANSWER-
ARIMA
Expected number of arrivals of people, things, etc. per
unit time -- for example, the expected number of truck
deliveries per hour to a warehouse. - ANSWER-Arrival
Rate
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. - ANSWER-Assignment Problem
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. - ANSWER-Attribute
Regression technique using past values of time series
data as predictors of future values. - ANSWER-
Autoregression
