setInitParams: Initializing kernel parameters
In GPrank: Gaussian Process Ranking of Multiple Time Series

Description Usage Arguments Value Author(s) Examples

Function for setting initial parameters to reasonable values after performing a grid search over parameters within their pre-set ranges. Loglikelihood is computed for each combination of parameter values on the grid, and those which lead to the highest loglikelihood value are set as initial values.

1	setInitParams(model, grid_size = 5)

`model`	GP model.
`grid_size`	Size of the grid over which the search for maximum likelihood will be done. Default value is 5.

Return GP model with the parameters initialized at reasonable values.
