Question

Consider the time series model
X₁ = u(t)+s(t) + εt.
Assuming the standard notation used in this module, what do each of the terms
Xt, u(t), s(t) and & represent?
In a plot of X against t, what features would you look for to determine whether
the terms μ(t) and s(t) are required?
Explain why μ(t) and s(t) are functions of t, whilst t is a subscript in X and εt.

Below are data on the population of a species of moths that inhabit an island and breed annually (then die). Suppose the population model has the form Pn= (1 + r) Pn-1 + f₂ where n is measured in years after 1995. That is, P = population in 1995, P₁ =population in 1996, etc. (a) You are to determine the updating function for this population using the data in the table above. Which of the following equations are valid for this model and can be used to find the parameters?

A scientist is studying three different cultures of bacteria {labeled "A", "B" and "C"} and wants to mathematically model the bacterial change of each type. To do this, the scientist decides to collect data for 25 consecutive days and builds the following scatter diagrams where the horizontal axis corresponds to "t" and the vertical axis to the amount of bacteria present in the culture P = P (t) Help the scientist decide which mathematical model (initial value problem) to use for each of the three types of crops. To do this, associate each of the graphs above with one of the following initial value problems. Crop type A a) dP/dt = k with P(0)=P0 and k>0.b) dP/dt = k with P(0)=P0 and k<0.c) dP/dt = kt with P(0)=P0 and k>0.d) dP/dt = kt with P(0)=P0 and k<0.e) dP/dt = kP with P(0)=P0 and k>0.f) dP/dt = kP with P(0)=P0 and k<0.g) dP/dt = kP(1-P/M) with P(0)=P0 and M, k>0.h) dP/dt = kP(1-P/M) with P(0)=P0 and M, k<0.
