chisq.gof.y: Chi-squared goodness-of-fit in forward dimension.

In david-borchers/hmltm: Line transect estimation with hidden Markov availability models

Chi-squared goodness-of-fit in forward dimension.

Description

Calculates Chi-squared goodness-of-fit in forward dimension, plots fit, and returns p-value and other stuff. Returns a data frame (goftable) with columns for start and end of bins, observed and expected frequencies in the bins, and the Chi-squared statistic for the bin. Also returns the Chi-squared statistic(X2stat), the degrees of freedom of the test (df), and the associated p-value (p.Chisq).

Usage

chisq.gof.y(fit, breaks, nys = 250)

Arguments

breaks	cutpoints on forward-distance axis defining bins
nys	number of y-values at which to calculate function before using approxfun approximate it at arbitrary resolution.
hmltm	fitted model, as output by est.hmltm

Details

Uses approxfun to approximate the forward distance pdf and then uses integrate to integrate it within each bin.
