positivedefinit: Bending and Check or Transform Positive Definite Matrix

In sknqualitasag/PositiveDefinit:

Description

Read csv-file of the variance component estimates and construct a matrix with this estimates by parts. This matrix is checked if she is positive definite or not. If this matrix is not positive definite, 2 functions may be called. If you put the paramter psOptionRatio = FALSE, makePD2() is called . For the parameter psOptionRatio = TRUE the function make_pd_rat_ev() is called. The difference is, that with make_pd_rat_ev() you have the option to whish a maximum ratio between largest and smallest eigenvalue.

Usage

positivedefinit(psInputFile, psOptionRatio = FALSE, psRatio = 100)

Arguments

psInputFile	input csv-file
psOptionRatio	TRUE or FALSE
psRatio	number
