Answer to Question #173556 in Math for ANJU JAYACHANDRAN

Question

8. (a) Give one example each from the real world for the following, along with justification,

for your example: (6)

(i) A non-linear model

(ii) A stochastic model

(iii) A linear, deterministic model

Answer 1

Non linear models are used in Global positioning systems signals for example a telephone receives signals from GPS satellites which have known orbital positions around the Earth

Stochastic models deals with models involving uncertainties or randomness. It is applied in the area of neuroscience. The release of neurones can be modelled as a passage time problem from stochastic processes. Analysis of Electroencephalography (EEG) signals from the brain makes good use of stochastic process

Deterministic model it assumes certainty in all aspects. Used in pricing structures for example if company's sales have increased steadily every month for the past few years conducting this model on the sales data with monthly sales the company could forecast sales in future months
