##Analysis

Create Total Incurred Cost per claim

df2 <- df
#summary(df2)
df2$TotalIncurredCost <- with(df2, TotalReserves + IndemnityPaid + OtherPaid - TotalRecovery)

Obtain the difference between closed and open dates to obtain the Claim Duration

df2$ClaimDuration  <- as.numeric(difftime(df2$ClaimantClosedDate, df2$ClaimantOpenedDate, units = c("days")))
#df2$ClaimDuration <- seq(from = df2$ClaimantOpenedDate, to = df2$ClaimantClosedDate, by = "day")
#summary(df2$ClaimDuration)
