loss_df: loss_df S3 class constructor
In merlinoa/lossdb: Automate common tasks involving insurance loss data sets

Description Usage Arguments Details Examples

loss_df is the primary S3 data class for the lossdb package. A loss_df is a data frame for insurance loss data. Each row/observation represents losses at a unique "origin", "dev", and optional "id" (i.e loss_df takes loss data organized by claim/occurrence "id", "origin", and "dev" or just by "origin" and "dev"). Each column contains certain variables of interest to the actuarial analysis.

1 2	loss_df(ldf, origin, dev, id = NULL, paid = NULL, incurred = NULL, paid_recovery = NULL, incurred_recovery = NULL, desc = NULL)

`ldf`	a data frame containing columns to be passed to `loss_df`
`origin`	policy period in which the claim/loss is associated
`dev`	development stage of claim/loss
`id`	optional identification key for loss (e.g. a claim number)
`paid`	vector listing names for all paid loss columns
`incurred`	vector listing names for all incurred loss columns
`paid_recovery`	vector listing names for all paid recovery columns
`incurred_recovery`	vector listing names for all incurred recovery columns
`desc`	vector of all additional columns relevant to the analysis. Common examples are "open claims", and "reported claims" (when claims are evaluated on an occurrence basis)

loss_df is designed to assign descriptive and consistent names to loss data to allow for quick execution of common actuarial analysis tasks.

# create loss_df object from `occurences` dataset
mydf <- loss_df(occurrences,  id = "claim_number",
                              origin = "origin",
                              dev = "dev",
                              paid = c("paid_loss_only", "paid_expense"),
                              incurred = c("incurred_loss_only", "incurred_expense"),
                              paid_recovery = c("sal_sub", "paid_excess250"),
                              incurred_recovery = c("incurred_excess250", "sal_sub_incurred"),
                              desc = "claim_cts"
                 )
