Musa-Okumoto Reliability Growth Model

Suppose I have data like this (day of test and defect(s) were found)

Day | Defect(s)

  1  |   10
  2  |   9
  3  |   6
  4  |   8
  5  |   4
  6  |   3
  7  |   5
  8  |   2
  9  |   1
  10 |   1

how to calculate µ(t) and λ(t) based on Logarithmic Poisson by Musa and Okumoto?

where,

µ(τ) = 1/θ ln (λ₀θτ + 1), and

λ(τ) = λ₀ / (λ₀θτ + 1)

I need to plot that calculated value. Please help.

Thanks in advance. Sorry for my english.
