2 coding question; function to write square root and given n, generate all permutations of 1:n. Background questions about resume and multicollinearity concept discussion
Main thing was working with normal probabilities and solving a equation system. The more complex point was N(1,1) + N(1,1) != N(2,2) but calculating the error propagation of the standard deviation.
You start at the origin and you can go either up/down or left/right. How far do you get in N steps. If there are two boundaries, what is the probability that you reach one before the other
From your knowledge what Point72 does
The outliers in linear regression, detection and solution.
If given a simulation result of 5 years and another simulation result of 10 years, how would you compare?
A NYC temperaure dataset. Asked to use linear regression to find the most predictive model.
The problems in the coding interview are not difficult for someone with a programming background. The interviewer asked me to evaluate the time-complexity and space-complexity of the algorithm and optimize it.
How do you predict the number of available bikes in a citibike station?
