summary.HL: Summary and print methods for fit and test results.

In spaMM: Mixed-Effect Models, with or without Spatial Random Effects

Summary and print methods for fit and test results.

Description

Summary and print methods for results from HLfit or related functions. summary may also be used as an extractor (see e.g. beta_table).

Usage

## S3 method for class 'HLfit'
summary(object, details=FALSE, max.print=100L, verbose=TRUE, ...)
## S3 method for class 'HLfitlist'
summary(object, ...)
## S3 method for class 'fixedLRT'
summary(object, verbose=TRUE, ...)
## S3 method for class 'HLfit'
print(x,...)
## S3 method for class 'HLfitlist'
print(x,...)
## S3 method for class 'fixedLRT'
print(x,...)

Arguments

object	An object of class HLfit, as returned by the fitting functions in spaMM.
x	The return object of HLfit or related functions.
verbose	For summary.HLfit, whether to print the screen output that is the primary purpose of summary. verbose=FALSE may be convenient when summary is used as an extractor. For summary.fixedLRT, whether to print the model fits or not.
max.print	Controls options("max.print") locally.
details	A vector with elements controlling whether to print some obscure details. Element ranCoefs=TRUE will print details about random-coefficients terms (see Details); and element p_value="Wald" will print a p-value for the t-value of each fixed-effect coefficient, assuming a gaussian distribution of the test statistic (but, beyond the generally questionable nature of p-value tables, see e.g. LRT and fixedLRT for alternative testing approaches).
...	further arguments passed to or from other methods.

Details

The random effect terms of the linear predictor are of the form ZLv. In particular, for random-coefficients models (i.e., including random-effect terms such as (z|group) specifying a random-slope component), correlated random effects are represented as b = Lv for some matrix L, and where the elements of v are uncorrelated. In the output of the fit, the Var. column gives the variances of the correlated effects, b=Lv. The Corr. column(s) give their correlation(s). If details is TRUE, estimates and SEs of the (log) variances of the elements of v are reported as for other random effects in the Estimate and cond.SE. columns of the table of lambda coefficients. However, this non-default output is potentially misleading as the elements of v cannot generally be assigned to specific terms (such as intercept and slope) of the random-effect formula, and the representation of b as Lv is not unique.

Value

The return value is a list whose elements may be subject to changes, but two of them can be considered stable, and are thus part of the API: the beta_table and lambda_table which are the displayed tables for the coefficients of fixed effects and random-effect variances.
