In timedeppar: Infer Constant and Stochastic, Time-Dependent Model Parameters

Draw indices for a random split of a vector into intervals of the same mean length

Description

This function draws indices for a random split of a vector into sub-vectors.

Usage

randsplit(
  n.grid,
  n.interval,
  method = c("modunif", "random", "weighted"),
  weights = numeric(0),
  offset = 0,
  min.internal = 2
)

Arguments

n.grid	number of grid points to divide into intervals
n.interval	number of intervals
method	method for random splitting: modunif modification of uniform intervals random random split (higher variability in inverval lengths) weighted random split with weights; non-normalized weights must be specified by the argument weights
weights	weights for choosing interval boundaries for method weighted; vector of length i2-i1+1 (does not need to be normalized and will be ignored for all methods except for method weighted)
offset	offset to shift subset of potential interval boundaries to draw from. To guarantee different intervals on subsequent calls, offset should be increased by one between subsequent calls for the same variable.
min.internal	minimum number of internal points between interval boundary points

Value

the function returns an index vector of length n+1 with the endpoint indices of the random intervals.

Examples

randsplit(100,10)
randsplit(100,10)
randsplit(100,10,method="random")
randsplit(100,10,method="weighted",weights=1:100)
for ( i in 1:10 ) print(randsplit(100,10,method="weighted",weights=1:100,offset=i))
