For the Student's t cumulative distribution function F ( x ; n ) with n ≥3 degrees of freedom, a corrected normal approximation, Φ ( λx ), is proposed as an extension of the well-known ordinary normal approximation Φ ( x ), where Φ ( x ) is the standard normal cumulative ...
terize this distribution in terms of parameters, such as the mean and standard deviation (for a normal distribution). For the present results, the first attempt is to test the hypothe-sis that the σt distributions are essentially single-valued, al-though incorporating random experimental errors...

"Log points" are a type of breakpoint that logs a message to the standard output without stopping program execution. When a log point is hit, the message is evaluated and printed to the console. The message can include interpolated expressions enclosed in curly braces{}, e.g.my_var is {...
