True or false: Bar charts are useful for comparing a single statistic (e.g. average, count, percentage) across groups. The height of the bar represents the value of statistic, and different bars correspond to different groups. - ️️True Assume that you are running Neural platform in JMP Pro. Which penalty method should be chosen if your data set has large number of X variables, and you think that a few of them contribute more than others to the predictive ability of the model? [ No penal...

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...
