Applications  (5)

Inflation  (1)

The following are spot oil prices from 1970 to 2010. This data is not corrected for inflation:

The consumer price index (CPI) is often used to correct historical prices for inflation:

Adjusted prices for inflation using the most recent value of the CPI:

Find the adjusted oil price on March 5, 2001:

Weather  (1)

The following are monthly average temperatures for a Missouri city over a three-year period. Separate the seasonal and nonseasonal components of this data:

Fit a model for the seasonal component:

Use the model to obtain the nonseasonal component:

Combining the components yields the original data:

Simulation  (1)

Use TimeSeriesMapThread to simulate a transformed random process:

Simulate WienerProcess:

Apply transformation to the random sample to obtain Brownian bridge:

Compare to the corresponding BrownianBridgeProcess:
