Team Leader

Responsibilities:

  • Segment customers into groups based on their protaintial probability of loss counts.
  • Assign different risk fator to each group of customers, make it convenient for Confidential to set up different price strategies for each group.
  • Clean the raw data with SAS/SQL
  • Due to the mistaken values in some variables, select the midel 90% data of those variables.
  • Create the target variable "sum" by adding up the total claim counts for each customer.
  • Employed the classification tree in SAS Enterprise Miner to select relevent independent variables for the target variable.
  • Selected 5 independent variables corresponding to the target variable "sum" from the total 57 associated variables.
  • Developed Zero - inflated negative binomial regression model to predict each customer's potaintial loss.
  • Firstly considered generalized linear models which can deal with event counts dependent variable: Poisson and Neg-binomial
  • Considered the fact that customers may or may not claim their loss to insurance company, the zero-inflated regression model was introduced into GLM models.
  • Employed SAS/STAT to estimated the parameters of each model, tested models by Voung test and Pearson Statistic, selected the zero-inflated neg-binomial regression model as the best one.
  • Used the final model to predict the expectated loss counts and claim counts for each customer.
  • Use the clustering analysis in SAS Enterprise Miner to segment all customers into groups.
  • Clustered customers into 40 groups by predicted claim counts and loss counts using least square method.
  • Sort the 40 customer groups by cluster's mean predicted claim counts and assigned each group with a risk factor. proc import, proc mean, proc freq, proc genmod, proc sgplot, proc transpose, macro.
