How do you do exponents in Stata?
exp(Z) returns the elementwise exponentiation of Z. exp() returns real if Z is real and complex if Z is complex. ln(Z) and log(Z) return the elementwise natural logarithm of Z. The functions are synonyms.
What is exp required in Stata?

- sqrt(a)—see [M-5] sqrt( )—calculates the (element-by-element) square root of a and returns the. result:
- Most functions work like sqrt(), although many take more than one argument.
- As another example, st view(V, i, j)—see [M-5] st view( )—creates a view onto the Stata dataset.
What coding language does Stata use?

What are bin plots?
A binned scatter plot partitions the data space into rectangular bins and displays the count of data points in each bin using different colors. When zooming into the plot, the bin sizes automatically adjust to show finer resolution. example. binscatter( x , y , N ) specifies the number of bins to use.
What is a binned scatterplot?
A binned scatterplot condenses the information from a scatterplot by partitioning the x-axis into bins, and calculating the mean of y within each bin. 5. Theoretically, this can also be done for quantiles in examining bivariate relationships without controls.
