QRM 7-3: TS for RM 2 (R studio)

Welcome to Quantitative Risk Management (QRM). In the last part of Lesson 7 we play with R studio, to better understand some of the topics we have discussed in the previous videos. We will deal with seasonality, we will simulate and estimate an ARIMA model, and we will perform model selec

QRM 7-2: TS for RM 2 (PACF, ARMA estimation and forecasting)

Welcome to Quantitative Risk Management (QRM). In the second part of Lesson 7, we first introduce the partial autocorrelogram (PACF) and see how we can combine it with the ACF to understand something more about AR, MA and ARMA processes. We then deal with the important problems of estima

How to determine if a set of points is a function, onto, one to one, domain, range

👉 Learn how to determine whether relations such as equations, graphs, ordered pairs, mapping and tables represent a function. A function is defined as a rule which assigns an input to a unique output. Hence, one major requirement of a function is that the function yields one and only one r

Mixture Models 5: how many Gaussians?

Full lecture: http://bit.ly/EM-alg How many components should we use in our mixture model? We can cross-validate to optimise the likelihood (or some other objective function). We can also use Occam's razor, formalised as the Bayes Information Criterion (BIC) or Akaike Information Criterio

Evaluate the limit for a value of a function

👉 Learn how to evaluate the limit of an absolute value function. The limit of a function as the input variable of the function tends to a number/value is the number/value which the function approaches at that time. The absolute value function is a function which only takes the positive val
