In statistical hypothesis testing, a turning point test is a statistical test of the independence of a series of random variables. Maurice Kendall and Alan Stuart describe the test as "reasonable for a test against cyclicity but poor as a test against trend." The test was first published by Irénée-Jules Bienaymé in 1874.
Statement of test
The turning point test is a test of the null hypothesis
H0: X1, X2, ..., Xn are independent and identically distributed random variables (iid)
against
H1: X1, X2, ..., Xn are not iid.
This test assumes that the Xi have a continuous distribution (so adjacent values are almost surely never equal).
= Test statistic
=We say i is a turning point if the vector X1, X2, ..., Xi, ..., Xn is not monotonic at index i. The number of turning points is the number of maxima and minima in the series.
Letting T be the number of turning points, then for large n, T is approximately normally distributed with mean (2n − 4)/3 and variance (16n − 29)/90. The test statistic

{\displaystyle z={\frac {T-{\frac {2n-4}{3}}}{\sqrt {\frac {16n-29}{90}}}}}
is approximately standard normal for large values of n.
Applications
The test can be used to verify the accuracy of a fitted time series model such as that describing irrigation requirements.

Turning Point Test: An Easy Way To Check Randomness
What is the Turning Point Test? B,C and E have turning points (either peaks or troughs). The turning point test is a test which lets us check whether a set of random variables are independent and identically distributed.
TIME SERIES - University of Cambridge
1.7 The turning point test We may wish to test whether a series can be considered to be white noise, or whether a more complicated model is required. In later chapters we shall consider various ways to do this, for example, we might estimate the autocovariance function, say {γˆk}, and observe whether or not ˆγk is near zero for all k > 0.

Testing i.i.d.: Turning point test Define T = |{t : Xt,Xt+1,Xt+2 is a turning point}|. ET = (n −2)2/3. Can show T ∼ AN(2n/3,8n/45). Reject (at 5% level) the hypothesis that the series is i.i.d. if T − 2n 3 > 1.96 r 8n 45. Tests for positive/negative correlations at lag 1. 14

Nov 5, 2013 · If you have three contiguous time points, assuming they are of different values. Then there are 6 permutations to order them. And four of them form a turning point (PEAK/PIT).
time series - the turning point test - Cross Validated
If $y_1, \ldots, y_n$ is a sequence of observations, we say that there is a turning point at time $i$, $1 < i < n$, if $y_{i−1} < y_i$ and $y_i > y_{i+1}$, or if $y_{i−1} > y_i$ and $y_i < y_{i+1}$.
