Three main categories of predictive modeling problems - Answer- 1. Descriptive - Focuses on what happened in the past and aims to "describe" or explain the observed trends by identifying the relationships between different variables 2. Predictive - Focuses on what will happen in the future and is concerned with making accurate predictions 3. Prescriptive - Uses a combination of optimization and simulation to investigate and quantify the impact of different prescribed actions in different sce...

Logistic Regression - Answer-Commonly used for modeling binary response data. The response variable is a binary variable, and thus, not normally distributed. In logistic regression, we model the probability of a success, not the response variable. In this model, we do not have an error term g-function - Answer-We link the probability of success to the predicting variables using the g link function. The g function is the s-shape function that models the probability of success with respect to...

What pieces of hardware are in the CPU? - Answer- Registers, ALU, and control unit Hardware which serves as the CPUs memory. There are special and general purposed of these - Answer- Registers Hardware which does arithmetic and logical computations - Answer- ALU Hardware which tracks state/status. Also controls other components - Answer- Control unit Instruction cycle responsible for loading the instruction - Answer- Fetch Instruction cycle responsible for finding the opcode/opera...

What is considered normal variability? correct answer: single results within 2 SDs (= within 95% confidence interval) Two types of statistical control charts correct answer: X-bar- continuous variables (quantitative results, TAT), allows to determine upper and lower control limits. p-chart- for binary parameters (e.g. yes/no responses when notification about critical values was issued). Calculation of upper and lower control limits for X-bar correct answer: Lower control limit = m - 3S...

How is data represented on a computer? Correct Answer-Use binary - the digits 0 and 1 - to store data. What is the type of a value? Correct Answer-A data type is a value type if it holds a data value within its own memory space. It means the variables of these data types directly contain values. All the value types derive from System. How does Java use types? Correct Answer-1. primitive type: these are pre-define in the language. 2. compound type (reference type) : these are some pre-defi...
