lambda - 2024 ACF Winter - Buzzpoints App

Question

An exponent denoted with this letter is the critical parameter of the Box–Cox transformation, which converts non-normal dependent variables to a normal distribution. For 10 points each:

[10m] Name this non-theta Greek letter that also parameterizes the Poisson distribution, as it equals both the expected value and variance.

ANSWER: lambda

[10e] If lambda equals zero, then the Box–Cox transformation just involves applying this function to the input data to make it normal. This function is the inverse of exponentiation.

ANSWER: logarithm [accept natural logarithm or ln (“lawn”)]

[10h] This plot is used to graphically check whether data is normal, as two identically distributed groups of data follow a 45-degree line. Comparing heavy-tailed and normal distributions on this plot produces a nearly horizontal line.

ANSWER: Q-Q plot [or quantile-quantile plot]
