This study investigated the effects of video tutorials on test scores for number series, another popular intelligence test task type. For this purpose, a parsimonious illustration model was developed forming the basis of a video tutorial explaining how to solve number series items. In an ...
In particular, your time series is very short, and you are only considering extremely long autoregressive lag lengths (p > 6). It will be difficult to estimate that many parameters with so few data points, particularly when you also have integration (d = 1 or d = 2) and when...
don't understand why it happens and I also don't know how to solve it. #!/usr/bin/python3 from pandas import Series s = Series(['foo', 'bar']) replace_dict = {'foo': 2, 'bar': 4} s = s.replace(replace_dict) I am aware of other questions and answers [2] but I don'...
The mathematical skills that are needed to make the connection between terms are not difficult. Brushing up on basic arithmetic knowledge is all that is needed to give you confidence for completing number series questions. 3) There may be more than one way to solve There could be more than o...
You say that this can only be solved by power-series methods but actually the substitution x = v' gives a separable ODE and SymPy can solve this: In [1]: v = Function('v') In [2]: m, c_d, rho, A, g, t = symbols('m, c_d, rho, A, g, t') In [3]: eq = Eq(m...

If you use Euler method to solve PVI (1)(1) numerically, you find the gradient descent method. Another choice is the curve satisfing the initial value problem (IVP) {Jf(u(t))u′(t)u(0)==−αf(u(t))u0,(2)(2){Jf(u(t))u′(t)=−αf(u(t))u(...
