[ ] Cluster . Clusterize the information creating different groups or type of entities
[ ] What are the probability to not be a Lead?
[ ] Hyphotesis creation, a discriminator to refuse what are not a lead
- [ ] Review different multivariable anyalysis methods
- [ [ Create an hypothesis is not a lead
- [ ] Calculate if the hypothesis is valid
- [ ] Create multihypothesis is not a lead

Analysis Multivariate Methods

Factorial Analysis(Components Principals). Reducing the number of parameters ( with more information ones)
- Variate have to be metrics(in this case is discrete, not continuous) o nominals
Cluster Analysis
- Element grouping
Multivariate regresion
Logistic regresion ( output is 0 or 1)

Steps Logistic regresion

Remove the outliers --> stadandaritzation
No High correlations among predictors (see correlation matrix less than 0.90 according with TAbachnick and Fidell 2013)
Variable reduction
Avoid overffiting ( less variables )

Machine Learning techniques

Classification without previous learning

ML and Logistic Regresion
