error_minimize3_raw: Minimize the Error for Raw Remaining K-mer Frequency

Description

This function minimizes the error for the raw remaining k-mer frequency by adjusting the scaling factor.

Usage

error_minimize3_raw(
  tooptimize,
  x,
  end,
  xfit_left,
  xfit_right,
  d,
  min_valid_pos,
  itr
)

Value

A numeric value representing the minimized error.

Arguments

tooptimize

A numeric vector containing the scale factors to optimize.

x

A numeric vector representing the histogram.

end

An integer indicating the right-side position for fitting.

xfit_left

A numeric value for the left-side position to calculate initial mean and standard deviation.

xfit_right

A numeric value for the right-side position to calculate initial mean and standard deviation.

d

A data frame representing the observed k-mer frequencies that will be fitted.

min_valid_pos

An integer indicating the left-side position from which the observed k-mer frequencies will be fitted.

itr

An integer representing the iteration count.

Examples

tooptimize <- c(1, 1, 1, 1)
x <- rnorm(100)
end <- 100
xfit <- seq(min(x), max(x), length=end)
xfit_left <- min(x) + 1
xfit_right <- max(x) - 1
d <- data.frame(V1=1:100, V2=rnorm(100))
min_valid_pos <- 10
itr <- 100

error <- error_minimize3_raw(tooptimize, x, end, xfit_left, xfit_right, d,
min_valid_pos, itr)
print(error)
