Suppose that the interval between eruptions of a particular geyser can be modelled by an exponential distribution with an unknown parameter ✪ > 0. The probability density function of this distribution is given by f(x; 0) = 0e0¹, x > 0. The four most recent intervals between eruptions (in minutes) are ₁ = 32, ₂ = 10, 23=28, ₁ = 60; their values are to be treated as a random sample from the exponential distribution. (a) Show that the likelihood of 0 based on these data is given by L(0) = 0¹e-1300 (b) Show that L'(0) is of the form L'(0)=0³e-1300 (4-1300). (c) Show that the maximum likelihood estimate of based on the data is 0.0308 making your argument clear.

Question
Suppose that the interval between eruptions of a particular geyser can be modelled by an exponential distribution with an unknown parameter 0 > 0. The probability density function of this distribution is given by f(x; 0) = 0e 0¹, x > 0. The four most recent intervals between eruptions (in minutes) are x₁ = 32, x₂ = 10, x3 = 28, x4 = 60; their values are to be treated as a random sample from the exponential distribution. (a) Show that the likelihood of based on these data is given by L(0) 04-1306 = (b) Show that L'(0) is of the form L'(0) = 0³ e 1300 (4- 1300). (c) Show that the maximum likelihood estimate of 0 based on the data is ~ 0.0308 making your argument clear. (d) Explain in detail how the maximum likelihood estimate of that you have just obtained in part (c) relates to the maximum likelihood estimator of for an exponential distribution.
