HPWmap: Computation of pointwise and highest pointwise probabilities.

Description

Pointwise (PW) probabilities and highest pointwise (HPW) probabilities of all differences of smooths at neighboring scales are computed.

Usage

HPWmap(smoothVec, mm, nn, prob = 0.95)

Arguments

smoothVec

Differences of smooths at neighboring scales.

mm

Number of rows of the original input image.

nn

Number of columns of the original input image.

prob

Credibility level for the posterior credibility analysis

Value

List with two arrays:

• pw: Pointwise probabilities (VmapPW) including the dimensions of the original input image, mm and nn.

• hpw: Highest pointwise probabilities (VmapHPW) including the dimensions of the original input image, mm and nn.

Details

HPWmap is an internal function of mrbsizeRgrid and is usually not used independently. The output can be analyzed with the plotting function plot.HPWmapGrid.

Examples

# NOT RUN {
# Artificial sample data: 10 observations (5-by-2 object), 10 samples
set.seed(987)
sampleData <- matrix(stats::rnorm(100), nrow = 10)
sampleData[4:6, ] <- sampleData[4:6, ] + 5

# Calculation of the simultaneous credible intervals
HPWmap(smoothVec = sampleData, mm = 5, nn = 2, prob = 0.95)

# }
