Multidimensional parallel Parametric Rao's index of quadratic entropy (Q)

Description

  x,
  alpha,
  window,
  dist_m,
  na.tolerance,
  rescale,
  lambda,
  diag,
  time_vector,
  stepness,
  midpoint,
  cycle_length,
  time_scale,
  debugging,
  isfloat,
  mfactor,
  np,
  progBar
)

Arguments

x	input list.
alpha	alpha value for order of diversity in Hill's Index.
window	half of the side of the square moving window.
dist_m	Type of distance used.
na.tolerance	a numeric value (0.0-1.0) which indicates the proportion of NA values that will be tolerated to calculate Rao's index in each moving window over x. If the relative proportion of NA's in a moving window is bigger than na.tolerance, then the value of the window will be set as NA, otherwise Rao's index will be calculated considering the non-NA values. Default values is 0.0 (i.e., no tolerance for NA's).
rescale	Scale and centre values in each of the element of x.
lambda	Lambda value for Minkowski distance.
diag	Boolean. Diagonal of the distance matrix.
time_vector	time;
stepness	numeric; steepness of the logistic function.
midpoint	numeric; midpoint of the logistic function
cycle_length	string; The length of the cycle. Can be a numeric value or a string specifying the units ('year', 'month', 'day', 'hour', 'minute', 'second'). When numeric, the cycle length is in the same units as time_scale. When a string, it specifies the time unit of the cycle.
time_scale	string; Specifies the time scale for the conversion. Must be one of 'year', 'month', 'day', 'hour', 'minute', 'second'. When cycle_length is a string, time_scale changes the unit in which the result is expressed. When cycle_length is numeric, time_scale is used to compute the elapsed time in seconds.
debugging	a boolean variable set to FALSE by default. If TRUE, additional messages will be printed. For de-bugging only.
isfloat	Are the input data floats?
mfactor	Multiplication factor in case of input data as float numbers.
np	the number of processes (cores) which will be spawned.
progBar	logical. If TRUE a progress bar is shown.

Value

A list of matrices of dimension dim(x) with length equal to the length of alpha.
