Factor Based Models classification, clustering, regression. Implicitly assumed that we have a lot of factors in the final model Why limit number of factors in a model? 2 reasons overfitting: when # of factors is close to or larger than # of data points.

Bernoulli Trial - An experiment in which there are exactly two possible outcomes Binomial distribution - A random variable X represents the number of successes observed from the n Bernoulli trials Binomial Parameters - n = number of trials p = probability of success q = 1-p Binomial probability function (f(x)) - E[X] binomial function - E[x] = np var(x) binomial function - var(x) = npq MGF binomial function - Additive property of binomial function - Sum of independent binomially dist...

classical definition of probability - ANSWER-If the process that generates the outcome is known, probabilities can be deduced from theoretical arguments, this is the ______ Relative Frequency - ANSWER-based on empirical data. The probability that an outcome will occur is simply the relative frequency associated with that outcome. subjective definition of probability - ANSWER-based on judgment and experience as sports experts might predict at the start of the football season—what is the p...

Random Variables correct answers It is a set of possible values from a random experiment. Discrete Random Variable correct answers Variable where the number of outcomes can be counted. For example, the number of white balls in a sample of size three is a discrete random variable which may take one of the values 0, 1, 2, 3 Continuous Random Variable correct answers is one that can take any value in an interval of the real number line, and is usually (but not always) generated by measuring...

multiplication rule - correct answer the number of ways to complete an operation is the product of the number of ways to complete each step permutation - correct answer an ordered sequence of the elements combination - correct answer a subset of r elements that can be selected from n elements where order doesn't matter probability of an event in a...

greedy algorithm - correct answer at each step, the algorithm does the thing that looks best without taking future options into consideration; more classical variable selection methods - correct answer stepwise - (forward, backward, combination) lasso elastic net available metrics for variable selection criteria - correct answer p-value r2 AIC / BIC lasso - correct answer Giving regression a budget to use on coefficients which it uses on most important coefficien...
