Methods

signature(size = "numeric", sizeNext = "numeric", cov = "data.frame", growthObj = "growthObj")

Methods to predict the probability density of sizeNext via linear prediction based around a range of transforms of the current size, and covariates described in the data-frame "cov". The prediction supplies mean sizeNext directly; the density function around this is normal.

signature(size = "numeric", sizeNext = "numeric", cov = "data.frame", growthObj = "growthObjDeclineVar")

Methods to predict the probability density of sizeNext via linear prediction based around a range of transforms of the current size, and covariates described in the data-frame "cov". The prediction supplies mean sizeNext directly; the density function around this is normal and the sd may change with size.

signature(size = "numeric", sizeNext = "numeric", cov = "data.frame", growthObj = "growthObjHossfeld")

Methods to predict the probability density of sizeNext using the Hossfeld function. The prediction supplies mean incr which is added to size to obtain sizeNext; the density function around this is normal.

signature(size = "numeric", sizeNext = "numeric", cov = "data.frame", growthObj = "growthObjIncr")

Methods to predict the probability density of sizeNext via linear prediction based around a range of transforms of the current size, and covariates described in the data-frame "cov". The prediction supplies mean incr which is added to size to obtain sizeNext; the density function around this is normal.

signature(size = "numeric", sizeNext = "numeric", cov = "data.frame", growthObj = "growthObjIncrDeclineVar")

Methods to predict the probability density of sizeNext via linear prediction based around a range of transforms of the current size, and covariates described in the data-frame "cov". The prediction supplies mean incr which is added to size to obtain sizeNext; the density function around this is normal and the sd may change with size.

signature(size = "numeric", sizeNext = "numeric", cov = "data.frame", growthObj = "growthObjLogIncr")

Methods to predict the probability density of sizeNext via linear prediction based around a range of transforms of the current size, and covariates described in the data-frame "cov". The prediction supplies mean logincr which is exponentiated and added to size to obtain sizeNext; the density function around this is log normal; and variance changes with size.

signature(size = "numeric", sizeNext = "numeric", cov = "data.frame", growthObj = "growthObjLogIncrDeclineVar")

Methods to predict the probability density of sizeNext via linear prediction based around a range of transforms of the current size, and covariates described in the data-frame "cov". The prediction supplies logincr which is exponentiated and added to size to obtain sizeNext; the density function around this is lognormal; the sd may change with size.

signature(size = "numeric", sizeNext = "numeric", cov = "data.frame", growthObj = "growthObjTruncIncr")

Methods to predict the probability density of sizeNext via linear prediction based around a range of transforms of the current size, and covariates described in the data-frame "cov". The prediction supplies mean incr which is added to size to obtain sizeNext; the density function around this is truncated normal, truncated at zero.

signature(size = "numeric", sizeNext = "numeric", cov = "data.frame", growthObj = "growthObjPois")

Methods to predict the probability density of sizeNext via linear prediction based around a range of transforms of the current size, and covariates described in the data-frame "cov". The prediction supplies mean sizeNext directly; the density function around this is poisson. NOTE THAT THIS EMPHATICALLY SHOULD NOT BE USED WITH AN IPM, SINCE THE PREDICTION IS NOT CONTINUOUS. It can be used with makeIntegerPmatrix.

signature(size = "numeric", sizeNext = "numeric", cov = "data.frame", growthObj = "growthObjNegBin")

Methods to predict the probability density of sizeNext via linear prediction based around a range of transforms of the current size, and covariates described in the data-frame "cov". The prediction supplies mean sizeNext directly; the density function around this is negative binomial. NOTE THAT THIS EMPHATICALLY SHOULD NOT BE USED WITH AN IPM, SINCE THE PREDICTION IS NOT CONTINUOUS. It can be used with makeIntegerPmatrix.
