findDistr: Fitting a Distribution

In sp2019-antibiotics/bacSplittR: Analysis of Antibiotic Resistance Data

Description

Fitting a n-fold multiple normal distribution with the parameters mean, standard deviation (sd) and n to a given subset of Data.

Usage

findDistr(df, startParams, fit, q)

Arguments

df	data frame, containing columns "diam" and "obs" which specify the Zone Data
startParams	numeric vector with start parameters for the nonlinear least squares algorithm
fit	criterion for the fit; default: "n_abs"; options: "Pmean", "Psd", "Pn", "sigma"
q	numeric value, giving the quantile of the distribution to be used as the ECOFF estimate

Details

The technique used is non-linear least squares, so the sum of the squared residuals is minimized.

Value

A numeric vector with the estimated ECOFF, mean, standard deviation, n and the fit value.
