By joining the variables rand1 and rand2 it means that both will be said by scratch cat when placed inside the say for 2 secs block. The rainfall the predictor variable and the following variable i e. The ratio variable is one of the 2 types of continuous variables where the interval variable is the 2nd.
In these cases you may call the preceding variable i e. Here type must be a valid c data type including char w char int float double bool or any user defined object. A variable is a characteristic while an attribute is its state.
